K&N Air Filters Reviews

Very nice

Reviewed By Josh G (WORCESTER, MA) Reviewed for a 2009 Subaru Impreza —3/19/2016 5:41 AM

I bought two of these, one for my girlfriends car and one for mine. 09 Subaru Impreza 2.5i and 10 Subaru Impreza 2.0. She noticed (10) a huge improvement in mileage and pickup. I noticed (09) a slight improvement in mileage but definitely a nice little sound and better low end acceleration. My car has 40K less miles than hers so maybe that's why she had the better mileage gain but we are both very happy and love the product. Easy installation, I sprayed the edges to create a seal when installed

It works.

Reviewed By Jeff D (FLAGSTAFF, AZ) Reviewed for a 2013 Subaru Impreza —4/8/2015 3:21 PM

Hard to tell what kind of impact (if any) this filter gave my wife's 2013 Subaru Impreza. I bought it because aFe filters are known to be great and it's re-usable. The price could be a little better.

Green air filter in 05 impreza 2.5RS

Reviewed By Ryan W (Brecksville, OH) Reviewed for a 2005 Subaru Impreza —10/20/2005 4:06 AM

I noticed increased midrange and high end power with this filter, which definitley helps with merging into freeway traffic. In the two tankfuls that I have had it, I have noticed a 7% decrease in fuel efficiency, but that could just be due to my ECU adujusting to the higher air flow.
