Very happy with the filter and price was much less expensive than buying it locally.
John Abelove, Indialantic, Florida
This air filter has made my Fiat come to life and reduce turbo lag. Fiats should come from the factory with these filters already installed. Better power, and gas mileage has gone up, and would definitely recommend others purchase this filter.

K&N filter fitment was excellent. Sound is more aggressive and performance is a little more spirited. K&N product are well made.
