K&N Filters Air Filter reviews

A must-have upgrade for the Fiesta:

Sharper throttle response

Smoother acceleration under load

Enhanced intake sound at full throttle

Maintains everyday usability while delivering a sporty edge when needed

More refined and controlled power delivery


You’ll notice the improvement immediately compared to a standard filter.

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

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 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

not much to say it let's out the turbo noise for a bit longer that I love in terms of performance barely noticed any difference

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

My first upgrade for every car - truly a lifetime air filter. I'm cleaning them every 8k km or 6 months. Never had a problem.

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