Parti Corrispondenti K&N STP SA10190 filtro aria

This is not my first K&N air filter. I have always seen a performance improvement and the cleaning kits last long enough to even out the cost of cheaper filters. I will keep buying K&N filters for the forseeable future.

This has made a difference to the performance of my struggling 1.4 petrol Auris. There is a steep hill on the outskirts of my town where my Auris can't maintain 60mph in 5th gear from bottom to the top. Old air filter: 60MPH in 5 gear at the bottom of the hill and time i reached the top, the car has dropped to 55MPH with the MPG reader recording 19.2MPG during the climb K&N air filter: 60MPH in 5 gear at the bottom of the hill and time i reached the top, the car went up to 61MPH with the MPG reader recording 18.6MPG during the climb Both Runs where done 2 twice (4 in total) on the same day.

After reading numerous articles in magazines and on the internet about your product I decided to purchase one. Easy replacement.
