K&N has released a composite custom racing assembly product number 100-8578 for sprint car applications. It is an air filtration solution for injector stacks that is large enough to flow enough air and mounts securely to prevent damage during a race.
K&N's 100-8578 Sprint Car Air Box
The 100-8578 is 4.375 inches in height and designed so it does not obstruct the driver’s view. Made with carbon fiber construction, this ultra light K&N sprint car air box is designed to increase horsepower while providing excellent engine protection.
K&N carbon fiber composites have cosmetic appeal and the stiffness to weight ratio that is needed to stay competitive while racing. Carbon fiber composites combine strength, durability and function along
with the right temperature. K&N’s advanced composite division has found the right mix with the
100-8578.
The K&N filter element is made of multiple layers of cotton and treated with K&N filter oil. This combination offers high airflow with little restriction, while at the same time provides excellent filtration to keep your engine running strong lap after lap.
K&N sprint car style air boxes are washable and reusable and come with a one-year limited warranty.
K&N has developed a new performance air intake kit, part number 63-1123 for 2004-2009 Yamaha YFZ450 Sport ATV owners. See the complete list of models below.

K&N dynamometer testing shows a 4.27 horsepower gain at 7200 RPM. This is well over a 10% power gain for power you can feel. K&N’s air intake design has lower restriction than the factory system. Once installed, you will notice the benefits of a less restrictive system.

The 63-1123 air intake system replaces the stock airbox and intake track with a complete rotomolded intake tube, a powder coated aluminum airbox and an oversized K&N high-flow air filter
part number
RU-4960XD. The K&N air filter is washable and reusable and provides excellent filtration. It is also pre-oiled and ready for installation.
The powder coated black heat shield assembly helps prevent rust and corrosion and isolates the K&N air filter from the engine compartment. This way the K&N air filter receives a consistent flow of fresh air.
There is also a K&N supplied remote mounted crankcase breather which helps keep the air filter cleaner and helps
to dissipate the extra heat and oils which generate from crankcase pressure.
Installation can be performed in 90 minutes or less. Take a look at our 63-1123 installation video to see all the steps involved.
A black K&N DryCharger filter wrap part number
RX-4990DK, is also included
for increased protection and longer service intervals in extreme dust or wet conditions. Jetting modifications will be necessary to obtain maximum performance. The
63-1123 is covered by the K&N Limited Warranty for one year.

The weekend started out with a chance of rain at his hometown track but it stayed away. That was the first good news of the night. The second good news was Rougeux managed to start 5th in the 2nd heat race. “There was a lot of lapped traffic and that held me up a little,” he said. “I managed to move into 3rd place with only two laps to go. That locked me into the lottery draw for the feature.”

Not only did Rougeux make it to the feature, he started on the outside pole position. “I took the lead from the green flag,” he said. “I was challenged by Dave Murdick for two laps and then I moved to the point position and never let go of the lead in 25 laps.” The third great news of the night was Rougeux made it to first place and ended up in the Winner’s Circle.
Team Rouguex races on tracks that consist of light powdered dust. “Our K&N air and oil filters protect our engines from that powdered dust and are just marvelous,” he said. “We get excellent filtration and additional horsepower.”
During the race there were several cautions, but Rouguex’s car was perfect on every restart.
“We’re trying to pick up our racing pace and move up in the Dirt Car Modified Series,” said Rougeux. “We’re trying different circuits which include 35 lap races.”
Team Rougeux will be back at Lernerville Speedway this weekend and then off to Canadaigua Speedway in New York for a 35 lap feature event.
Rich Tobias, of Speedway Entertainment, has made it his goal to offer affordable racing technology that really gets results. Tobias created the Slingshots racing division in an effort to show that affordable racing is competitive and exciting. Racing has been in the Tobias family since the mid 1950's. Rich Tobias' Uncle Lawrence was the original Toby Tobias, and then his father Dick Tobias took on the nickname and made it nationally known. "When Tobias Speed Equipment began building race cars in the Lebanon, Pennsylvania shop, it was apparent that this was what I wanted to do, both as a fabricator and a driver," says Rich.
Slingshots are a 39 horsepower vehicle powered by a Briggs & Stratton Vanguard engine capable of speeds near 100 MPH.
Speedway Entertainment is currently the home to the fastest growing class of race cars in the United States today. It has been ten years since the launch of the "Slingshot by Tobias" class and counts have grown to over 400 cars being raced in 17 states. "The SpeedSTR's were created to give another stepping stone for Slingshot drivers and in our 2008 Inaugural Season, we were able to demonstrate that affordable racing does have a place on the local racing scene," says Rich. The Slingshots are a 39 horsepower vehicle powered by a Briggs & Stratton Vanguard engine capable of speeds near 100 MPH. They are designed to look like the dirt track modifieds that are popular in the northeast. The SpeedSTR's are powered by a Dodge Neon engine and have 250 horsepower propelling the 1,100 pound open wheel cars around the speedways. "The flip wing on the SpeedSTR gives some added stability but both classes rely on chassis setups and driver talent, says Rich. "Slingshots and SpeedSTR's are both spec classes and can be raced on asphalt and dirt surfaces with minimum changes."
Currently, the Slingshots have no age boundaries with drivers from ages 6 to 81 strapping into them from coast to coast.
"Knowing that K&N Air Filters are installed on the Slingshots and SpeedSTR's gives me the satisfaction that all engine components will be protected to the fullest extent, says Rich. Performance is of the utmost importance with the lower horsepower race cars where every advantage can make the difference between winning and losing. "The fuel injection system used on the SpeedSTR's can be finicky and with four stacks needing protection, K&N has shown that their design and performance have exceeded our expectations.
Currently, Speedway Entertainment is looking to expand their SpeedSTR horizons. "Ray Evernham Motorsports, Canada based RevStar, and Doug Herbert Performance are all becoming more involved, getting the word out about the affordability of the SpeedSTR and the fact that it is becoming an excellent alternative to big car spending while getting the same results for a race team," says Rich. The Briggs & Stratton National Championship Tour for the Slingshots has grown to include speedways in Florida and Minnesota. RevStar is now making them available to Canadian racers with a tour scheduled for 2010.
Speedway Entertainment started out as a company building full caged indoor karts. With the advent of micro-sprints and the success of go-karting, Rich Tobias developed the Slingshot in 1999 to give drivers of all ages a chance to not only be race fans, but race drivers. Currently, the Slingshots have no age boundaries with drivers from ages 6 to 81 strapping into them from coast to coast. The SpeedSTR's found a new surface to race on with the advent of the Ice Racing League in Montreal. Studded tires are a must as the SpeedSTR's circle 3/8th mile ice tracks in full competition with temperatures dropping as low as 15 below zero.
Both classes are still growing and both the SpeedSTR's and Slingshots do not leave the Speedway Entertainment shops without anything but K&N Air Filters serving as protection for all racing surfaces. "With K&N Air Filters we know it's a product we can trust at a good price for our Affordable Racing Technology," says Rich. "K&N Air Filters are dependable, reliable and can withstand the constant abuse that dirt track racing exerts on an engine. They are very easy to change and in this business, time means everything, so with the simple twist of a screwdriver you are ready to compete. Design means a lot in racing and the streamlined design of K&N filters make a perfect fit for all of our race team needs."

“Kevin and Kent Gerhardt worked hard all night to get the car ready so I could be competitive for the feature,” said Lewis. “We were off somewhat with our qualifying effort so I knew I had to work hard during the race. I was able to get a good start as well as good results during the feature. It means a lot to me to get a win for the Gerhardt family at their home track.”
Because of Lewis’ feature win, both Western Speed Ford Focus midgets are now ranked in the top 3 in points of the USAC California Pavement Ford Focus Car Series. Lewis is in 6th position and teammate Cody Gerhardt is in 2nd position.
“When they show up, everyone knows the team is ready to do business,” said K&N Sports Marketing Manager Tony Yorkman. “K&N is happy to be a part of it and looks forward to the rest of the season with two sprinters and two midgets running with Toyota power and K&N air filters and oil filters.”
Lewis and Gerhardt will race next May 30th at All American Speedway in Roseville, California.
"We want to thank K&N for their support and outstanding products," said Lewis. "The K&N filter is a very important component to help protect our engine, increase the airflow, and offer the extra filtration we needed to help us win by 10 car lengths."
