    5.0 out of 5 stars Perfect fit for my 99 Ram 2500 Cummins
    Reviewed in the United States on December 7, 2023
    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!

    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!

    5.0 out of 5 stars K&N Filter
    Reviewed in the United States on August 29, 2022
    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 in
    I 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
