K&N Air Filters Reviews

Best Filter Made

Reviewed By Carl M (Bellmawr, NJ) Reviewed for a 2009 Subaru Forester —12/22/2010 10:32 AM

As a fan of K & N filter, I have them in all my cars and trucks, they are great, lowest maintence item on any vehicle. Clean them every 25, 000 to 30,000 miles, beats replacement normal filters. Plus the gas saving, okay, you get mayber 1 or 2 better mpg, but it is still a savings. Just install this one in my HEMI, was getting 13.2, now getting average of 14, this is with using the remote start for 5 or 10 minutes in the COLD mornings. Buy one, install it, you will see for yourself, more power, better mph, and no replacement of normal filters.

Aem for subaru forester

Reviewed By Francis G (Jim Thorpe, PA) Reviewed for a 2017 Subaru Forester —9/6/2016 11:01 AM

When I installed the filter my avg mpg went up 2mpg from 26 to 28. I am relieved that the map sensor won't be getting oil on it from the filter.

Subaru 2011

Reviewed By Anthony L (Island Heights, NJ) Reviewed for a 2010 Subaru Forester —7/31/2016 7:26 AM

The filter works well, however my vehicle is on recall due to this make & model having oil consumption issue. the vehicle can consume btwn 1 & 2 qts. between 7 thousand mile oil changes. Subaru is going to evaluate my car the next oil service and advise about problem. This problem may be the cause of my low MPG. & horsepower issue.
