    Good upgrade for F-550

    Posted by Michael on Jul 8th 2020

    Added this to my 2001 F-550 as it was a birthday gift from my wife, it was the blue Donaldson with the hardware included. Work with many different non-highway Diesel engines for a few different companies, all have used Donaldson filters most of our diesels are out living the hour meters great filters great prices here. 20 minutes 4 beers and you have a noticeable upgrade for your 7.3L, thanks

    This had an immediate Impact on the performance of my engine and it’s abilities to get more air which in turn means faster acceleration. I would recommend this product to anyone and will continue to get more
    RiffRaff parts.

    Hardest part was taking the old airbox out (easy). This kit is too easy!
