Great product. The stock filter on the vehicle I bought this for is incredibly restrictive, and there was a noticeable increase in power and a slight boost in fuel economy immediately after install. Very worth it.

Bought this air filter for my 2017 Buick Envision and it provided another 1.5 per gallon gas mileage to 35 MPG on our round trip from Dallas TX to Minneapolis MN. Total mileage was 2150. Great product because I have had gas mileage improvement like this in my last four vehicles.
