Noticed better throttle response. Slightly improved gas milage. 1 mpg better.
Joseph Dalba, Mansfield, Texas
Didn't get the results I was expecting from all the other K&N filters I have used. My 2017 XT5 is averaging 23 mpg which is within 1 mpg of what I was getting with the stock filter.
Jerry Farris, Montrose, Colorado
I've been using K&N Air filters for 30 years. Currently have K&N on three vehicles including my Harley. Wouldn't use any thing else. I always recommend K&N to everyone.
