K&N 33-5056 Air Filter Product Reviews

Wednesday, April 12, 2017 - Part 33-5056
I've been using K&N Air filters for 30 years. Currently have K&N on three vehicles including my Harley. Wouldn't use any thing else. I always recommend K&N to everyone.

This filter increased my horsepower and increased my mpg, by 4 gallons. A must have for any car. Much better than a paper filter.

2017 Acadia seems much better with the K&N Air Filter. Can't wait to get it on a road trip and see how much better the gas mileage is. I have K&N air filters in the other two vehicles I have and I am very pleased with the improvement.

K&N filters are the best. Quality, performance and reliability, not to mention increased torque, performance and mileage.

So far so good. Product appears to be a great fit and of quality construction, as in my past experience.
