After two races into the Formula Drift season, Matt Coffman and his Coffman Racing team, backed by K&N Filters, are in 25th place in the Pro standings.

Matt Coffman was excited about the first event on the Formula Drift schedule. It was on the Streets of Long Beach, one of his favorite circuits. He maneuvered his K&N Filters backed Nissan through the course during qualifying on the Friday before the race with tremendous confidence. It was raining and Coffman was in his element.

Matt Coffman lost in the first round in the Formula Drift season opener at the Streets of Long Beach, in California. He lost in the first round at the Formula Drift event at Road Atlanta, in Georgia.

“I feel like I’m the only professional out there when it rains,” Coffman said. But the online comments he read after qualifying were not flattering. They were extremely critical. Drivers were crashing and spinning out. Coffman was one of the few drivers who did not have any problems. He said the people making online comments were talking nonsense about Formula Drift. “I have been trying to tell people don’t drag me down with them,” he said, “I’m not like them.”

It has been a bit of a slow start for the Coffman Racing team. Coffman is 25th in the Formula Drift Pro standings after two events. Vaughn Gittin Jr. leads the pro standings with 155 points. After two races into the Formula Drift season, Coffman entered a rally race in Washington. It gave him a little diversion from the Formula Drift scene. Plus, it gave Coffman a chance to compete in the form of racing he really loves.

Coffman lost in the first round battle to Forrest Wang at the event on the Long Beach Grand Prix Street Course in California in April. Wang advanced to the quarterfinals and lost to Kenshiro Gushi. In addition to the rain and slippery track, Coffman said his emotions took over in his first-round battle against Wang.

“The first round was good for us because it rained substantially,” Coffman said. “All the other drivers were wrecking and they were changing tire pressures, they were jumping around on the suspension changes, all sorts of stuff. They were still crashing and still laying down terrible runs. We were going out there and absolutely killing every run consistently.”

When it came time to race, Coffman was already running on high gear. He couldn’t wait to get on the track. Because his emotions were running so high, he made some mistakes. Looking back, Coffman said he wished he dialed it down a bit before his first run.

“Something in my mind will tell me to go 1,000 percent more,” Coffman said. “It cost me to mess up on that round, unfortunately. That round, I can’t blame the car, I can’t blame anything except for myself on that one. That was me just pushing 10 times harder than I needed to.”

Coffman admits Wang took advantage of his mistakes. Wang didn’t overdrive the course and kept his car and his emotions under control.

In addition to racing in Formula Drift, Matt Coffman entered a rally race in Washington. He is headed to Orlando, Fla., next week for another Formula Drift event.

“Forrest was actually doing pretty decent,” Coffman said. “When I went against Forrest, he did a lot better than I thought he was going to. I didn’t take the line that I should have. It was my mistake.”

“Forrest was actually doing pretty decent,” Coffman said. “When I went against Forrest, he did a lot better than I thought he was going to. I didn’t take the line that I should have. It was my mistake.”

“He really did run away faster than I thought he was going to,” Coffman said about his first-round race against Stoneback. “If you talk to anybody, it was a very evenly matched run. He just had more distance on me than I had on him. But as far as mess ups, there weren’t mess ups on either side. It was a very even battle.”

The next Formula Drift event is in Orlando, Fla., at Orlando Speedworld from June 3-4. Coffman said he is looking forward to competing on a wide-open, fast track, like Orlando, as opposed to the tight, choking tracks at Road Atlanta and Long Beach.

“It is the only track where I legitimately have to modulate throttle toward the end of my second run otherwise I will run out of tire,” Coffman said. “I like really high-speed tracks.”

In addition to starting the Formula Drift season, Coffman and his team entered a rally race in Washington. He recently competed in the Olympus Regional Rally, a three-day event in the Pacific Northwest. Driving with Michael Kulawiak, the team finished in 18th place overall in their 2008 Subaru Impreza STI in the first of two North West Regional Rally races at the event. The team ran into trouble on the course on the second day and did not finish. Coffman and Kulawiak were entered in the Super Production class and was the runner-up in the division.

 “Whenever we kind of get a little bored of drifting, we are all like maybe we should probably go back to a rally race,” Coffman said. “Rally racing is almost like a confident knowledge that we win every single time.”

While Coffman said he doesn’t know when he will enter another rally race, he prefers it over Formula Drift for a number of reasons. If anything, it helps improve his devotion to auto racing and motorsports.

“In rally racing, I can just get out of the car and I can turn around and I am just in this gorgeous valley or forest,” Coffman said. “It really has become a spiritual thing for me, rally racing. It is something very special to me.”

The K&N Filters his team uses in his Formula Drift cars really make a difference on the track. Coffman said before he started using K&N air filters, his team had a hard time creating decent air flow through the cars.

“Our engines would be nothing if they couldn’t breathe,” Coffman said. “There was nothing we could find that wouldn’t suffocate the motor or take away from something at one point. They were the only company that offered us a box that made it perform perfectly.”

But Coffman said he notices a big difference using K&N filters in his rally cars. The K&N air filters have to be efficient in all types of environments, from high-altitude forests to swamps and valley riverbeds.

“With our rally car, we have to keep three-quarters of a ton of dirt out of the air box,” Coffman said. “The only thing standing between that and the motor is the K&N filter really.”

Kyle Benjamin won the pole for the NASCAR K&N Pro Series East race at Dominion Raceway, in Virginia.

Spencer Davis won the NASCAR K&N Pro Series East race at Dominion Raceway, in Virginia, by the narrowest of margins. Track officials needed to review a photo finish to determine the winner. Davis crossed the finish line 0.005 seconds ahead of Justin Haley.

Spencer Davis won the first NASCAR K&N Pro Series East race of his career at Dominion Raceway.

For Davis, one of the drivers selected to the NASCAR Next program, it was the first win of his career. It came in his 10th career K&N Pro Series East start. He was the runner-up in the first two races of the 2016 K&N Pro Series East season.

“That long dramatic pause was about to push me over the edge,” Davis said. “When I heard my name over the intercom, everyone started screaming over the radio. And it was the best burnout I’ve ever done.”

Davis led the last 13 laps of the ComServe Wireless 150. He took the lead on a restart following a multicar crash on lap 138. Kyle Benjamin, the pole winner, was collected in the four-car crash and was knocked out of contention. Benjamin, who entered the race as the leader in the K&N Pro Series East standings and another driver selected for the NASCAR Next program, led the first 137 laps of the race. After the crash, he fell to last place and finished in 23rd place.

Davis and Haley battled for the lead over the last 12 laps of the race. Davis didn’t forfeit the lead, but the two drivers were neck-and-neck on the final lap around the .4-mile track. The two cars crossed the finish line simultaneously, but Davis edged Haley by a fraction of a second.

Spencer Davis, one of the drivers selected to the NASCAR Next program, led the last 13 laps and won the K&N Pro Series East race at Dominion Raceway, in Virginia.

“He shoved me off into the corner, just like I would do it if I were in that position,” Davis said. “Everyone is going for the win. That was old-style short track racing right there, beating and banging coming to the checkered. I don’t think you could have scripted something better.”

The end of the NASCAR K&N Pro Series East race at Dominion Raceway in Virginia was a photo finish between Spencer Davis and Justin Haley. Davis, in the No. 41 car, won the race by 0.005 seconds over Haley.

Noah Gragson was third, his first top-five finish in six K&N Pro Series East races. Kaz Grala was fourth, followed by Austin Theriault in fifth.

Haley moved into first place in the K&N Pro Series East standings. He has a 19-point lead over Benjamin after six races. Haley has five top-five finishes and one win in six races. Benjamin finished outside the top 10 for the first time this season.

Davis moved into third place in the K&N Pro Series East standings after winning his first race of the season. The 17-year-old rookie is 23 points behind Haley for the lead in the K&N Pro Series East standings.

The next K&N Pro Series East race is the Stafford 150 at Stafford Motor Speedway, in Connecticut, on June 17.

K&N 63-1131P air intake for the 2008-2011 Harley Davidson Twin Cam 96 V-Twin and 2009-2015 Harley Davidson Twin Cam 103 V-Twin

One of the most endearing features of a Harley Davidson^® motorcycle is that throbbing V-Twin engine. They've been making them since 1909, and the 2008-2011 Harley Davidson Twin Cam 96 V-Twin and 2009-2015 Harley Davidson Twin Cam 103 V-Twin, are two of the most advanced "potato guns" to date. You get dual camshafts, electronic fuel injection, and a host of other innovative features, all wrapped in a sturdy big-bore package. The low-down torque of the Harley^® the 96ci V-Twin and Harley 103ci V-Twin prove that there really is no replacement for displacement. But you can squeeze more horsepower and torque from your air-cooled monster, with the K&N 63-1131 AirCharger performance intake system.

Every Harley Davidson motorcycle turns its drive-wheel by combining gas and air inside its twin-cylinders. This power cocktail is then ignited by the spark plugs, and the resulting explosion sends the piston downward, turning the crankshaft, and eventually the back wheel. But in order for the gasoline to burn in that explosion, oxygen has to be present. That catalyst comes in through the paper air filter, located behind the cool looking chrome cover on the side of your big Harley engine. The problem is, the aesthetics of the bike limit the amount of air that can flow into the throttle body, which ultimately dictates how much power your Harley Twin-Cam engine can make. The K&N 63-1131 AirCharger performance air intake kit addresses this issue, by creating a more direct airflow path to the cylinders. And, it looks a whole lot cooler than the factory lid.

But of course, talk is meaningless without the proof to back it up. So to verify the performance of every cold air intake, K&N conducts before & after dyno tests on the vehicles each system was designed for. Since the K&N 63-1131 performance air intake system will work on both the Harley Davidson Twin Cam 96 V-Twin and Harley Davidson Twin Cam 103 V-Twin, they tested a 2015 Harley Davidson Electra Glide 103 ci, and found that it made 68.20-hp and 87.77 lb-ft at the rear wheel with the Harley Davidson factory air intake and 75.00-hp/94.81 lb-ft with a K&N Harley Davidson air intake. That's an estimated increase of 6.80-hp and 7.04 lb-ft, which you'll certainly notice when you twist the throttle.

The K&N 63-1131P air intake system boosts power on the 2008-2011 Harley Davidson Twin Cam 96 V-Twin and 2009-2015 Harley Davidson Twin Cam 103 V-Twin

Features & benefits of the K&N 63-1131 air intake system:

If you're looking for more than an air intake, K&N makes a lot of other motorcycle performance parts to fit your Harley Davidson. To have a look, use the search by vehicle tool, or to find a K&N dealer near you use the dealer search tool.

K&N carbon fiber intake tube 100-8522 is the mandated intake system for the NHRA Pro Stock class. It consists of two carbon fiber intake tubes, a billet throttle body adapter, two couplers, and hardware.

The only constant in life is change. This saying is becoming more and more true as we progress further into the 21st century. While we aren't riding true hover boards or commuting in flying cars, we have still seen huge changes in all aspects of our daily lives. This is especially true in regards to the technology we use on a daily basis.

These changes can even be seen in some of the most iconic American sports. The additions of the shot clock in basketball, instant replays in baseball, and electronic fuel injection (EFI) in motorsports have all caused a ruckus of one sort or another in their respective fields. When NASCAR made the switch to EFI it signaled a major change for auto racing. While most changes are widely accepted, there has been a bit of resistance to the switch to EFI, even though it has been present in motorsports since at least the 1950s. This may be because people were accustomed to carburetors or maybe because it was relatively easy to make big power with carbs, but whatever the reason, the pushback hasn't seemed to stop the transition.

Most recently, NHRA announced that they changed the regulations for the Pro Stock class and made the switch from carburetion to EFI. In order to do so, there were a lot of associated changes that needed to be made. When NASCAR mandated EFI in 2012, it was made simpler because they were already using the standardized, Car of Tomorrow, chassis.

With NHRA's switch, they made changes not only to the engine but to the exterior body of the cars and the intake tract. "When the NHRA switched the Pro Stock class from carburetors to fuel injection, they came to K&N to design and manufacture an intake system," explained Steve Williams, Chief Engineering Officer at K&N Engineering. "There aren't a lot of times where the sanctioning body, OEMs, chassis builders, and spec parts suppliers have worked so closely together on a project like we did on this one."

There are hundreds of combinations of body, engine, and intake manifold that the race teams can build. K&N had to keep this in mind and create a system that would be able to be adapted to any of the combinations.

One of the initial problems was the system had to work with every combination of body, motor, and intake manifold that the teams could possibly build. This made an interesting predicament because NHRA only mandated that the throttle body remain within the engine compartment at all times. But it did not limit where in the engine compartment it had to be. As a solution, K&N's new intake system is a two-piece design with a pair of couplers that help the teams adapt it to the location of their throttle body.

"Another problem with the switch is that NHRA removed hood scoops as a method for air intake," added Williams. "This meant that the inlet had to move to the front bumper." The regulation for this inlet is a maximum size of 80 square inches. "This is where we ran into the next issue. The air close to the track is much hotter than the air three or four feet up." This is an issue that teams will have to combat, with help from the EFI manufacturer, Holley. Thanks to the almost unlimited tunable nature of EFI, these kinds of things are able to be accounted for. Carburetion would often cause some pistons to be either too rich or too lean but with EFI, teams can adjust for each piston on each shift during each segment of the run. They can also account for things like air temperature changes throughout the day.

"Even with all the issues presented to us and the short time frame, we were able to work with NHRA, Holley, the race teams, and chassis builders to create an intake system that made the switch to EFI a lot easier," revealed Bert Heck, Performance Kits Manager for K&N Engineering. "After NHRA made the announcement, we had about two months to design, test, and manufacture a kit for all the teams. That is not a lot of time, but with days to spare, K&N 100-8522 carbon fiber intake tube was ready to be shipped to all the Pro Stock teams in time for the first race of the season in Pomona."

Major changes are going to happen and with everyone working together toward the common good, big things can happen. The EFI switch in Pro Stock couldn't have happened without the cooperation and assistance from everyone involved. It just goes to show that even though these teams go out and battle each other week after week, in the end they are willing to come together and help one another out.

A secondary frame for the K&N 33-5026 is part of the installation to ensure a proper seat for the filter inside the Sonata and Optima air box.

In the insecure days of the Great Recession of 2008-2011, many drivers had to tighten their belts, and run hard to stay in one place. Not everyone could buy a new car every 2-4 years. If they did, they bought economy cars and tried to keep them sound and in service longer. Hyundai and Kia were at the top of the value-priced list for the compact and family-sedan segment. With increasingly better build quality, more attractive sheet metal shapes, and the company's 360-degree/lifetime warranties, these cars became the transportation investment of choice for the value-minded. That the current Optima also won the 2016 Red Dot "Best of the Best" international design award is another acknowledgement to constant improvement.

Consistently lauded by automotive reviewers are the features and benefits being perfected and integrated into Hyundai and Kia products. Safety and technology upgrades have been largely successful, with the 2015 Sonata and 2016 Optima earning perfect five-star overall crash-test ratings in U.S. government testing.

Further, if you're keeping the Hyundai Sonata or Kia Optima as a car for your kids to drive in a few years, most models now come with emergency telematics systems (crash response, speed/geo-fencing, curfew limits, and roadside assistance), plus rearview camera, blind-spot monitoring, and cross-traffic alert.

The K&N 33-5026 replacement engine air filter for the Hyundai Sonata and Kia Optima is a rectangular panel constructed of a special oiled cotton gauze that can be cleaned and reused.

Approximately 1.1 million Hyundai Sonatas and 928,560 Kia Optimas were purchased in the U.S. from 2009 to 2014.

Fast forward to 2015-2016 where repeat and new customers are still buying the South Korean marques and want to keep their new cars "new" and healthy. Beauty and health come from within and begin with maintaining a clean air induction system, starting with perhaps the most important part: the engine air filter.

The 2015 and 2016 Hyundai Sonata and Kia Optima share near-identical 2.4-liter inline 4-cylinder, 2.0-liter turbocharged 4-cylinder, and 1.6-liter turbocharged 4-cylinder engines, and all three need the same sort of air filter service approximately every 50,000 miles (depending on driving conditions).

If performed by you or your mechanic, it is a straightforward operation that ensures free-flowing fresh air for your Hyundai or Kia's induction system. It is especially important for turbocharged engines since they use even more air, and a step-up replacement air filter like the K&N 33-5026 will enhance acceleration and are designed to boost horsepower and acceleration.

K&N's 33-5026 engine air filter fills this bill and is a direct replacement for the stock filter in both the Sonata and Optima. It is a drop-in design manufactured from a special oiled cotton gauze and mounted in a polyethlene frame. It comes with an additional plastic frame to create an even better fit in the air box. Installation requires no tools and can be accomplished in about 5 minutes.

The K&N 33-5026 filter will last the life of the vehicle, especially when cleaned with products formulated specifically for it and available in the K&N 99-5000 filter care service kit.

When it is time to check or clean the filter, simply reverse the installation steps, and clean and refresh the cotton gauze using K&N's 99-5000 filter care service kit.

If you're keeping your Sonata or Optima for a while, the investment in a K&N 33-5026 washable, reusable engine air filter is the logical, economical, and ecologically sound path to engine health. With regular service, it can last the lifetime of the vehicle and is backed by K&N's Million Mile Limited Warranty.
