Very happy with the filter and price was much less expensive than buying it locally.

K&N Air Filter No.33-5015 fits perfectly in the air box of our 2015 Fiat 500L 1.4L Turbo. So far, so good. Fuel mileage a bit better overall despite colder fall/winter weather. Say, would you please send me a self-adhesive label that says a K&N Air Filter is installed in our car's air box? One did not come in the box of our new filter. Your service was prompt and I'm glad to have purchased this air filter from your factory location. Maybe you will please make a cabin air filter for our 2015 Fiat 500L??? Thank you very much. K&N rocks! Rich Withers, Veradale, WA
