K&N has developed a one-of-a-kind carbon fiber top and base air filter (RP-5115) that is oval shaped for the 2005 and 2006 Chevrolet SSR. There is minimal clearance under the hood on the 2005 SSR, but after extensive research and development K&N designed an air filter that is the perfect size specifically for this vehicle.

To immediately see the benefits of a K&N air intake kit simply replace the SSR’s original intake assembly with the 57-3055. Cooler outside air is drawn through our washable and reusable K&N air filter for more power and filtering capacity. It fits into the engine compartment using factory holes and mounting points. A powder coated steel heat shield replaces the stock air box and protects the K&N air filter while isolating it from engine heat.

This K&N air intake system can be installed in 90 minutes or less and is backed by the famous K&N Million Mile Limited Warranty.

The factory air box is restrictive in size and restrictive in air flow.

It takes less than 90 minutes to install this K&N air intake system to eliminate air path restriction and allow virtually free flowing air into your engine. K&N air intake systems also come with the famous K&N Million Mile Limited Warranty.

The high flow technology invented by K&N and made in the USA provides the best balance of airflow and filtration. The RC-5046 cone shaped air filter is also washable and reusable and can go up to 100,000 miles before cleaning is necessary.

Boldly Redesigned 2008 and 2009 Jeep Liberty Gets 11.25 Horsepower Boost with K&N Air Intake

Jeep's popular Liberty model received an aggressive makeover for 2008. Bold lines, modern round-headlights, and that unmistakable vertical-slat grill compliment the very capable Liberty package. Seeing the potential for improvement K&N Engineering seized the opportunity to build one of their Performance Air Intake Systems (57-1559 and 57-1559) for the 2008 and 2009 Jeep Liberty with the 3.7L V6 engine.

With the addition of K&N Engineering's Performance Air Intake Systems (57-1559 and 57-1559), Liberty owners can realize a gain of more than 11 horsepower. K&N's Research and Development Department tested a 2008 Jeep Liberty 3.7L V6 on our in-house dynamometer. Results showed an impressive 11.25 horsepower gain @ 4800 RPM.

K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten airflow. This allows your engine to pull in air with ease compared to the OEM air filter assembly. More air means more power and torque when you need it. With a K&N Performance Air Intake System, consumers can count on extra horsepower whether driving around town, towing, or hauling five passengers plus gear on a camping trip.

These air intake systems use a conical shaped chrome top high-flow air filter (RF-1048) and powder coated aluminum heat shield in place of the vehicle's stock air box. The result is an air filter that captures harmful particles, provides more surface area, flows more air, and has a long service life. This K&N air filter performs for up to 100,000 miles before service is required depending on driving conditions. Improving the air path between the filter and the motor is the rotationally-molded high-density polyethylene tube. It offers the most flexibility in design and outstanding horsepower numbers. It takes about 90 minutes or less to install this system with simple tools. It is covered by K&N's Million Mile Limited Warranty.

“That second place win set the stage for the remainder of the weekend,” said Brian Folk. “Nick drove his Wegner Racing Engines powered LS-1 Camaro to the top qualifying spot and moved up the ranks.” Nick Folk took the victory and now has the lead in IHRA Stock Eliminator points. He is also a step closer to take the podium as the 2008 World Champion.

Brian Folk maneuvered his Camaro Roadster through a talented Super Rod field to the finals. He battled Jimmy Lewis, the runaway points leader in 2008 Super Rod championship points. Folk defeated Lewis, even thought the two left the starting line in unison.

“I was just lucky in the final,” said Brian Folk. “When we got near the finish line, he was ahead and I just gave up. Then I looked up and my win light was on. I couldn’t believe it.”

The Folk family uses K&N Products on all their vehicles. “Our K&N air and oil filters are the best on the market,” said Folk. “The dirt stays out of our engines and the filtration is great which gives us a competitive edge on the track."
