Purchased filter for my 2017 Cadillac XT5... It was a perfect fit. However that came as no surprise as I have been using K&N filters in all my cars for the past couple decades and they have always been a perfect fit.

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.

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.
