I love K&N air filter products. I installed this for my cold air intake on my puckup. Fit perfectly and works great.

Works great. I purchased it as a second so when I change my oil and clean my air filter I don’t have to wait for it to dry!

Had to get a 4" aluminum pipe (bought a spectre that was recommended on the page) to connect to my factory intake and made a small bracket to go over the stud on the filter. I used some self tapping screws to fix the bracket to the fender. Filter fit great, the factory filter minder fit in the end of the filter perfectly. Now I have all of the turbo noises lol. Price was hard to beat!

Solid K&N filter. The small hole at the end is for a filter minder.K&N filter minder part number (sold on Amazon) K&N 85-2445 Filter Minder; Push inI suppose you can cover the hole with a bold and washer, or anything else that you don't want sucked into the turbo.All in all, a nice add on for 5.9 Cummins
