Just installed the K&N filter in my 2017 GMC Sierra 1500 with a 5.3L. Always been a fan of K&N filters. I'll track to see if gas mileage improves.

I bought the filter hoping that it would increase my gas mileage. It did by only by 1-10th of a gal. My mileage showed I was getting 19.1 mpg, and after putting in the K&N it improved to 19.2. Oh well it was worth trying.

I have used K@N filters for many years and have been extremely pleased with them. The value and performance is great. The reason for 1 star has nothing to do with the filter. The installation was easy once I got through Chey's poor design. The fourth screw holding the filter cover is directly under two pipes and extremely hard to get to. Secondly Chevy's instructions on how to remove the cover left one step off and without that step I could not have removed the cover to install a new filter.
