K&N Air Filters Reviews


A Breath of Fresh Air

Reviewed By Robert R (Bruceton Mills, WV) Reviewed for a 2004 Hyundai Elantra —7/16/2007 4:30 AM

I am currently installing K&N air filters on my 3rd vehicle. My original was in a 2004 Hyundai Elantra for 85,000 miles. As far as I know, it still is in the car performing fine. The only thing that was done to the filter was cleaning and re-oiling. My gas mileage was increased by 1-3 MPG. I just installed K&N filters in my 2006 Elantra and a 2005 Ford Freestyle. It is too early to evaluate the MPG gain, but I anticipate a 5% to 10% gain in each vehicle. Keep up the good work!!!

K&N Cabin Air Filters Reviews


Cabin Air filter

Reviewed By David C (MONROVIA, CA) Reviewed for a 2011 Hyundai Elantra —12/9/2015 8:46 AM

The cabin air filter is great. It will save me hundreds of dollars over the life of my car at $16 per replacement or $50 per year. Plus I bought the cleaning kit too.
