K&N Air Filters Reviews


Pleased with my new K&N filter.

Reviewed By John S (Wichita, KS) Reviewed for a 2003 Porsche 911 —4/4/2012 6:45 PM

The filter fit well and looked to be well-constructed. Felt and sounded like some improvement in engine performance and sound. I'll need to avoid over-oiling it whenever I clean it...which should be a long time from now. Only drawback might be less efficiency than a paper filter, thus engine oil get dirty more quickly.

great buy!

Reviewed By Nathan W (Cleves, OH) Reviewed for a 2012 Ford Focus —5/25/2017 6:23 AM

Recently purchased a 12 Focus SE to keep miles off my RS. Wanted a good air filter mainly to help maximize fuel economy but any performance gain is certainly welcome too. Super easy install, left the factory box lid ON as it really forms a very nice and effective 'cold air' intake. The open end produces a nice and appropriately (minor and subtle) throaty noise under load. Great buy, definitely pick one up!

Reviewed By Daniel B (SAINT PAUL, MN) Reviewed for a 2016 Chevy Silverado —5/25/2017 4:23 AM

Went with this instead of the whole air intake system. I think I did good. Have seen about 2 miles per gallon difference. Throttle response is great. It has been installed for about a month.2016 chevy 2500 HD 6.0 motor
