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

Noticed better throttle response. Slightly improved gas milage. 1 mpg better.

I recently purchased a 2017 G.M.C. Acadia Denali, and as I do with all of my vehicles, I installed a K&N air filter in it. The highway rating on it is 25 M.P.G. The day after I installed the filter I took a 600 mile trip up to Michigan and back and was more than pleased. I averaged 33.3 M.P.G. I highly recommend K&N products to everyone.
