"One of the reasons for such a large power gain is the large K&N Air Filter (RF-1048)," said K&N Performance Kit Manager Bert Heck. "The factory air box was restricted in size and restrictive in air flow especially at higher RPMs. We made a larger intake tube that fit nicely under the front stabilizer bar."

"The tube is oval because the throttle body was oval. This also allowed the tube cross section to be larger," said Heck. "The large horsepower gain of this air intake is also due to the radius adaptor design as it smoothly takes the 6 inch flange of the air filter and mates it with the intake tube."

It takes less than 90 minutes to install this K&N AirCharger Air Intake System to virtually eliminate air path restriction and drive a massive amount of air into your engine. K&N Air Intake Systems also come with the famous K&N Million Mile Warranty.
