K&N filter for 99 Impreza

Reviewed By Keith H (Allenstown, NH) Reviewed for a 1999 Subaru Impreza —10/30/2007 12:58 AM

Went from a dirty paper filter to this and you can definitely feel a difference, especially when merging on the highway or passing (pedal to floor & car downshifts). Power is noticeable at the peak powerband of the vehicle (seems to want to open up more easily). It looks like Im going to get about 15-20 extra miles to a tank w/ this filter.

Green air filter in 05 impreza 2.5RS

Reviewed By Ryan W (Brecksville, OH) Reviewed for a 2005 Subaru Impreza —10/20/2005 4:06 AM

I noticed increased midrange and high end power with this filter, which definitley helps with merging into freeway traffic. In the two tankfuls that I have had it, I have noticed a 7% decrease in fuel efficiency, but that could just be due to my ECU adujusting to the higher air flow.

Tight fit

Reviewed By Daniel W (Rochester, NY) Reviewed for a 2011 Infiniti G37 —10/1/2015 4:47 AM

I almost didn't think they were going to fit....that's the only bad thing I can say about it. They come with a nice sticker alerting the grease shops that there's a washable filter so they don't throw it out. Pre-oiled and looks like nice n sturdy construction.
