This is the second K&N replacement filter I have purchased and installed in my vehicles. Both have worked extremely well and improved performance as well as gas mileage in my vehicles. I highly recommend K&N filters.

Filter had a positive impact on MPG. I was skeptical but it really improved by two to three MPG city /HWY combined.

Definitely improved milage on my 2014 toyota 4runner. The buying experience was good. Shipping took a bit longer than most things I buy online but it worked.
