K&N Replacement Air Filter

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.

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 have only had this product in my truck for a couple of days, but it appears to have improved the engine response. Gas mileage check will have to wait until I drive a bit more.
