K&N 33-5040 Air Filter Product Reviews

Easy swap in my 2017 Fiat Spider. It fit a little loose compared to the original. I seem to notice a difference at low rpm which seemed backward to me. When really getting on it, I can't say I notice any difference but it's hard to tell. I know K&N to be a great performance filter so I'd recommend it regardless of any performance gain I had with this car.
