"They provide that I control the air flow and can get it clean whereever I am when needed." —Norman C from Angelus Oaks, CA bought a K&N Air Filters for a 2008 Subaru Forester, 2.5L 4-cyl. engine.
"Had/have K&N air filters in every vehicle I have owned (cars, motorcycles, atv's, and golf carts). Unfortunately, the K&N air filter on my 2008 Subaru Forester Sports XT does not fit perfectly. It's close, but not perfect." —Dwayne I from Fernley, NV bought a K&N Air Filters for a 2008 Subaru Forester.
"Has made a difference in overall response in accelerating and spunkiness. I had a 1/2 tank of gas in tank when installation was made; after first fillup, overall average mileage went from 25.5 to 26.4. This is just back and forth to town, etc. No long trips. I anticipate to gain another mile or two per gallon. I gained more than 2 miles per gallon on my 99 CRV when K&N filter was installed, so I believe I will do as well or better on my new Subaru. I used the 07 K&N filter on my 08 as the service dept. at my dealer said it would fit and he too recommended the filter." —Kenneth Or Teresa L from Dunnellon, FL bought a K&N Air Filters for a 2008 Subaru Forester, 2.5L 4-cyl. engine.
"I considered the cone shaped performance filter with a cold air box but opted for a K&N replacement of the stock filter instead. I'm sure it breathes better with the new filter and it feels a little more eager from a dead stop.
I have used a K&N filter before in a VW Golf.
I have a round cannister filter in my Dino that looks like a K&N but it is a different brand." —David L from Erie, CO bought a K&N Air Filters for a 2008 Subaru Forester, S-type, 1.6L 4-cyl. Engine.
