Didn't get the results I was expecting from all the other K&N filters I have used. My 2017 XT5 is averaging 23 mpg which is within 1 mpg of what I was getting with the stock filter.

I have used several K&N filters in the past. This latest air filter for my 2017 GMC Acadia was a super easy installation. Great product.

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