This is now the 10th filter we have had from K&N for our fleet Land rover Discovery 4 commercial and standard cars, more performance, more fuel economy and we would not hesitate to have another. Thank you K&N. regards, Simon.

Excellent service from K&N as expected and the quality of my panel filter is excellent and was extremely easy to fit in the existing air box. I prefer the quality of K&N Filters over any other and love the difference it makes to my Range Rover Sport compared to a standard filter and the fact that it will outlast and out perform any other that I have tried. Thank you K&N for excellent quality filters.
