"I have experienced gas saving and a nomal boost in Horse power. Factoring out the life of this K&N filter the saving in the long run are tremendous." —Richard C from Fort Wayne, IN bought a K&N Air Filters for a 2008 Subaru Outback.
"I have K & N in both my cars. Are they better than other filters, I don't know for sure, I'm going by the data provided about air flow and life. I figure that if a regular filter cost $7-8 & are replaced every 7-8k miles, the cost averages out about the same. If performance is better because of K & N, then I've come out ahead. Plus I like the idea of cleaning & reusing instead of just replaceing." —Tom H from Tulsa, OK bought a K&N Air Filters for a 2008 Subaru Outback, 2.5L 4-cyl. engine.
"I have a K&N in my Pathfinder, Jetta, and my wife's new Outback. Each vehicle has a K&N filter. My wife is averaging about one or more miles per hour with the filter. Whereas for my vehicles I don't know because I got the filter when I got the vehicle." —Reino T from Arvada, CO bought a K&N Air Filters for a 2008 Subaru Outback.
"I have had 3 subarus and they all ran better with a clean air filter. With the K & N installed the shifting is smoother and the engine is running easier. It seems to have more power requiring less down shifting. Only in for a few hundred miles but there is an increase in gas milage. The K & N is better than the stock filters. I have no worrys about dirt. We use K & N in our Dirt Modified race car." —Walter R from Newark, DE bought a K&N Air Filters for a 2008 Subaru Outback, 2.5L 4-cyl. engine.
