Air filter fit perfectly. Direct replacement of the original filter in my Jaguar X Type 2.5 V6. Great service from the supplier. Parts were delivered quickly and the website was very easy to order from. I would definitely recommend you use this company. I will definitely use again many thanks on my next vehicle what ever it will be.

I have used K&N filters on several vehicles over the years and in each case there has been a small but noticeable improvement in throttle response, in some cases, coupled with a reduction in fuel consumption. These benefits and the re-usable nature of the product make these filters a must have for me.

Having bought a new car in May of 2015 one of the first things I decided to do was change the air filter to the K&N type. I have used K&N filters for many years now on all the cars my family has run. There was an immediate improvement in engine performance. I like that once a year all I have to do is to wash the filter out to restore the original level of performance.
