I have been using K&N filters for many years. I like that you don't have to keep replacing them every service. Also they have a better air flow over standard filters.

Amazing filter.

I’ve always used K&N air filters for my cars. Started with my Mini Clubman 1978 model with a Weber setup. Gave great increase in performance and driving experience. Now I’ve also upgraded the twin air filters to K&N for my Range Rover Sport Supercharged and the feeling is great.

Very fast shipping, easy install and great value for money. Vehicle feels a little more lively via "the pants in the seats" dyno but not sure if I gained any horsepower. Would definitely recommend
