2000 Pontiac Trans Am, 5.7L with automatic transmission, 70,000 miles on the engine. After putting long tube headers and full exhaust on my car, I finally put a K&N air filter on my car. Instant gains in low-end throttle response and seat-of-the-pants feeling. I would not doubt gains of 5-7 RWHP throughout the entire RPM band.

I just wanted you to know we have many opportunities to verify hp improvements with K&N Filters and were always impressed even in custom applications we fabricate using a K&N Filter and our intake tubes. Recently we ran a 1999 Pontiac Firebird 5.7 on our Dynapack chassis dyno and saw a 10 hp improvement @ the wheels in a completely stock vehicle with the stock replacement K&N part number 33-2118. We must say that no matter what K&N is a huge improvement over stock. If you are questioning whether or not you should purchase one, stop now and pull out your checkbook and order yours today! Once again my hands are in the air.
K&N, We salute you!

Bought a 2004 Hyundai Accent base factory. Bought the car used so it wasn't taken care of. Replaced all the plugs, wires, and fuel filter and jumped gas mileage from 19 to 24. After replacing the air filter with a K & N Filter gas mileage went to 32 MPG !! Changed the oil with synthetic with a K & N oil filter and got 37 MPG next tank !

K & N Rocks !!

Have installed K & N air filters on every vehicle ranging from the Hyundai, a 95 Camaro, 2003 Chevrolet Silverado and now a 97 Dodge Avenger. Waiting for the filter on the Avenger to come in, but know it will give performance and gas mileage that is unbelievable.

Found multiple people at auto part stores buying filters before - and told them the advantages of buying a  K & N performance filter, and it changed their mind from the $ 6 paper junk filter.

Keep up the great work K & N, love your products !!

need to study exhaust systems...that would rock to make a K & N Muffler !
