K&N 33-2318 Air Filter Product Reviews

Friday, May 12, 2017 - Part 33-2318
I noticed a difference in my car immediately after putting in the K&N air filter. It ran smoother, had more power and gas mileage improved. I highly recommend this product.

Hard to prove but haven driven the Buick for nine years I feel that acceleration is better, not much but better and highway response as well.
