A quality product. Easily fitted as a replacement filter on my 1996 Jaguar XJ6. The car is definitely driving better with a noticeable improvement in acceleration especially under heavy use of the throttle and in lower gears. Only reason for 4 stars vs. 5 is that I believe fuel consumption has got slightly worse, not better. Highly recommended if you want a better breathing car...

Had used K&N filters in my dirt bikes years ago. Getting great performance in my 76 VW van.
