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

Best filter around

Reviewed By Matthew M (Sunnyside, WA) Reviewed for a 2010 Subaru Impreza —4/4/2017 8:18 AM

I've only had the filter installed for a week or two and the engine already is performing better and has better pickup and mileage.

2003 wrx (300+ hp)

Reviewed By Karl G (Rochester, MN) Reviewed for a 2003 Subaru Impreza —7/1/2016 6:14 AM

Best air filter I've ever had. About 2/3 more surface area than a k&n and it's cheaper! Afe is well known in turbo diesel applications, and has proven itself on my ej207 boxer motor
