"Have another month of testing mileage but KN filter seems to be delivering 1 - 1.5 mpg improvement. Filter cleaning should probably be done more frequently than each 50,000 miles even under normal conditions. However, if it continues to deliver more air for more efficient combustion, it would be worth it to clean more often (say each 25,000 miles under normal conditions)" —Robert B from Casper, WY bought a K&N Air Filters for a 2005 Subaru Legacy.
"Ive noticed an increase in throttle respose and the sound of the blowoff valve is more enjoyable." —Robert P from Crown Point, IN bought a K&N Air Filters for a 2005 Subaru Legacy.
"I have only installed a K&N filter in my cars. I installed this in my 2005 Subaru Legacy GT. Decided not to go with a cold air system since I wouldn't be doing any mods to the turbo or exhaust. It has a nice little aspiration sound on acceleration. I have seen about a 2 mpg increase in gas mileage which is great for a drop-in filter. The throttle response definitely feels quicker." —Vincent A. M from Goshen, NY bought a K&N Air Filters for a 2005 Subaru Legacy.
