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.

Installed in a 1999 Jeep Grand Cherokee. A perfect fit replacement for the old throw-away filter. The Jeep air filter box is easier to open than the one on my Mazda Miata. The Mazda was the first K&N filter I bought and it was great - real performance improvement. The Jeep is no sports car and with only 4.0 L and a moderately heavy SUV, I need as much performance as I can get. A good investment for cars I intend to keep a long time.

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 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.

This is my first ever K&N product. I've always heard good about the filters. The push was a disposable filter from the auto store was $25.00. K&N was $53.00 for life. It's a no brainer. Just clean it in what 18 months? Great buy.
