Installed this filter today as a replacement for my stock airfilter. I'm definitely noticing the performance improvement! No more turbo lag and quicker response. Directly ordered K&N filters for my other cars. I can definitely recommend the K&N air filters and I'll use it on all my car's from now on :-)

Fitted new K&N filter on return trip across Sahara Desert. Noticeable improvement in performance and fuel consumption on original filter. Filters changed or cleaned every 200 miles or sooner so K&N worked out cheaper and more effective. Very pleased with product. Easy to fit.
