    Intake/Exhaust

    Posted by Unknown on May 7th 2017

    Installed a 4" exhaust with an eliminator pipe, this air filter and the truck ran like it was really breathing for the first time! Awesome bang for the buck!

    High flow top quality. Expanded metal inside and outside so there is no worry about collapsing and getting sucked into your turbo. Definitely will buy another.......

    Bought this filter for my 01' F250. Great product and even better price!
    Also bought the filter sleeve that slips on for extra protection.
    FAST shipping to Texas too!
    Thanks, Caly

    Can't beat RiffRaff Diesel!

    I've been running this filter for years and it's excellent. Durable, great flow, easy to service, great whistle, and so easy to get from RiffRaff at nearly half the price of NAPA. At least the last time I checked. Delivered so fast it'll make your head spin! Thanks RiffRaff for the best parts, at the best price, and of course the best service.

    Great filter for a custom intake system on my 7.3L Excursion

    Posted by Chris on Nov 13th 2016

    I used this filter as part of a custom intake build I did on my 7.3L Excursion and it has been awesome. The increased airflow over stock is evident from the truck letting out almost no smoke when accelerating hard on a mild tune, and from the sound of the air moving. The filtration seems to be good; I have yet to see any dust/dirt in the turbo, and have shaken off a fair amount from the outside of the filter. It looks great too on its own or with the riffraff filter cover, which I also bought.
