Greg Wilmot, Glendale, California
Very happy with the new replacement filter for my Jeep Grand Cherokee, Thank you!
Rob Taylor, California
I have used K&N filters in all of my vehicles for the past ten years. Performance does increase slightly off the line but highway cruising at 65-75 gets me 21-23 average mpg out of the 4.0L and a little more kick when the throttle is pressed. I have never noticed any dirtier oil or experienced premature wear using these filters.
Austin Dowell, Universal City, Texas
Great filter, definitely see an increase in throttle response and fuel economy. Well worth the money.

I've been using K&N air filters for ever. Never had one fail. I wish it was like the old days when they were in the old buildings off of Iowa in Highgrove. You could stop by and get an adaptor for a Fj40 or whatever. That first filter I boughtmust have been a foot tall but they helped me make it fit. Getting old so this could be my last truck.
