K&N Filters: reviews and customer ratings

Probably the best filter out there, its more expensive when you buy it but it last almost forever just clean it and put it back, and the airflow is also greater then the stock ones, its god for us people that little more boost than stock

It's one of the best brands, if not the best, that produces materials and components for every kind of cars including this air filter which last a long time. It's well made and engineered to give the best performance to our cars

exeptional performance gain, car feels much more linear power gain and also makes a bit louder sound on idle, which is I think due to gow filter works. Had it for over two years, would not take any other air filter.

I have used K&N filter on my Triton pickup truck and I have been happy with the easy of cleaning it and putting it back into the engine filter box. Enjoy the ride with it for 3 years on my Triton 2010 pickup truck.

Tested on the dyno on my previous car Audi A7 Bitdi.It really delivers what it says on the tin,slight increase in hp and torque plus better induction sound.I'm looking forward to have it fitted on my tuned Golf R.

I have been using them on my Mustang for years. I loved that they came with the stickers to write down the mileage and put them on your front window. Apparently that’s no longer the case, such a shame!

I chose this item because it’s the best air filter for my car and it definitely made a difference to my car not only noise but speed to I think at a cheap price too from AUTODOC

Excellent upgrade for my car
Can hear and feel the difference straight away
Not sure if it’s made it any faster but definitely worth while upgrade

Thanks Autodoc, this filter is probably one of the best out there, is washable and high flowing and therefore cost lite extra

fit perfectly Honda civic fn2, it's perfect for the performances and it make the noise a little better
I would buy again !
