Great filter last a lifetime and improved my mileage by 2 miles per gallon with better top end power with less turbo lag. I put K&N filters in all my vehicles! Always have always will!

When replacing stock filter with K&N filter the canister has a hole in the side in which the stock filter has a section of foam that seals it off but the K&N does not. Hopefully it is okay to leave the hole open. Other than that I could feel the difference in performance. Would like to know if leaving the hole open is okay.

Original filter has foam attached to side of element that covers a hole in the air filter housing. the K&N filter does not have this foam to cover the hole. Contacted K&N, they said the foam is not needed. Using the K&N filter causes a whistling sound at certain speeds.
