Surprising results in 8-passenger crossover vehicle

Reviewed By Bobette B (Wildwood, MO) Reviewed for a 2008 Mazda CX-9 —9/19/2008 8:41 AM

I've used K&N in most of my previous sports cars and performance sedans with excellent results (particulary when paired-up with a free-flowing exhaust updgrade). Given the skyrocketing cost of fuel, I decided to try one in my wifes's '08 Mazda CX-9. To my surprise, the filter resulted in an immediate increase of 2 mpg (mixed loop), and a "seat-of-the-pants" gain in low end acceleration. The 3.7L six even seems to idle a bit quieter. At this rate, payback on the investment in the filter will arrive in 2 1/2 months.

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.
