K&N 33-2446 Air Filter Product Reviews

Massive difference to my Range Rover Sport. Pulls better, gear changes are smoother. Finally the big V8 can breathe. Very happy.

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.

I'm glad this kit has 2 filters, one for each side of the engine, so that I don't have to buy two separate ones. The kit includes two different K&N stickers, so I can put one on each intake.

Have had these filters on my last 2 Discovery 4's and my earlier Discovery 1. Also have one in my Triumph thunderbird and think they're great. Love the fact I can just keep re using them also. Less landfill and better performance!
