Austin Dowell, Universal City, Texas
Great filter, definitely see an increase in throttle response and fuel economy. Well worth the money.
Jan J., Santa Barbara California
Have used K&N filters for over 35 years now. My '91 Grand Cherokee 4.0 has run well with this filter, have cleaned it once in 105K miles and gives me about 21.5MPG on the open road at 65-70mph. Many trips from Santa Barbara to the Redding area have shown it to be consistent. Best bang for the $$ for this vehicle.

Fit perfect in a '99 Jeep Grand Cherokee Laredo. Very pleased with the product, price and quick delivery.

Mario Lopez, Colorado
19 mpg with aftermarket air filters - 21 mpg with the K&N!! Cleaning and recharging is a snap and saved me from buying another disposable filter. Impressed enough that my wife's '06 Forester and my '97 Wrangler now have K&N's. I clean all 3 at the same time to save time and no longer buying throw aways saves me money!!

I have used your filters in all of my many vehicles, including Honda Goldwings. I find the filters are excellent (I have noticed I can get your filters at Walmart a few dollars cheaper, but have always ordered direct from you guys). Keep up the good work.

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.
