*Note: Anodized Color on Aluminum can be discolored / damaged by chemical engine cleaners. Use only soap and water to clean.

*Fitment Note: The hardware included with the plenums is intended to secure the plenums and GPR/AIH bracket only; if the fuel line clamp and AIH ground wire will be re-used, customer will need to make provision for the reinstallation of those items. We suggest the RDP-FFL line kit in place of the stock fuel lines.

    Must Have For Anyone Producing Over 23 PSI

    Posted by Beau W. on Feb 23rd 2024

    These billet intake manifolds are a work of art. Exceptional quality, function and looks. My stock plenums RTV gaskets blew out due to my truck producing 27~32 PSI. These billet plenums w/ the o-ring style gasket fix and surpassed my issue. Highly recommend these to anyone boosting over 23 PSI.

    Excellent Design

    Posted by Jack Adams on Feb 14th 2024

    These are by far the nicest addition to my 2002 7.3 I have done. Stainless hardware, and the machining is perfect. Easy install once you get your stock plenums off and clean all that nasty rtv off the heads.

    These are awesome!

    My flat plate style plenums started leaking. Replaced them with these. The gain in performance is amazing. They are well worth the money to buy them.

    Quality Part

    Posted by Kyle Dixon on Dec 8th 2023

    Well thought out and well engineered part. This bolted up to my 2001 7.3 just like it should, and the oring seal is so much better than the stock RTV. The stainless steel hardware that is included is a nice touch as well.

    Look amazing

    Posted by Michael Powers on Oct 3rd 2023

    The fit is perfect and they look amazing! Hug difference in valley. The O'ring seal is very hard to install and keep in place. It should of been a square seal and not round and make the groove deeper so it sits in place better. I'm just hoping it didn't roll or pop out when i installed them.

    Hands Down the Best

    Posted by Jason Evans on Jul 19th 2023

    Not all parts are created equal. Learn from my mistake, and dont trust parts just by their name. I purchased a set of "billet" plenums from another diesel shop online because they were more expensive than Riffraff's and the pictures looked ok. Well it was a terrible mistake, they didnt have oring seal, only RTV, had cheap hardware store bolts instead of stainless, and the "machining" looks like it was done with a table top router instead of CNC. It was completely 1 dimensional an worse flow than stock. In the end I had to sell them on eBay just to get rid of them and purchased these from Riffraff Diesel. What a difference! The machining is amazing, exactly and off the charts on flow profile. If you are serious and want quality parts Riffraff is the only way to go. These guys are top notch and have the best customer service. I regret ever purchasing from someone else, I got bit and paid the price but hope that by sharing you wont and can learn from my mistake.

    Great Product, I can breath!

    Posted by Ronney on Jun 6th 2023

    A repair shop recently damaged one of my plenums so badly, it was not reparable with riffraff insert rings. So I decided to spend a few bucks more and get the billet plenums.
    Easy to install once you have everything cleared out of the way. The hardest part was the oring gasket if you can call that hard. Follow the directions, call riffraff if you questions and they will help pretty darn quick.
    No more leaks, no one can damage them, no more blowby. Peace of mind.
    My wife even likes them.
    I notice a difference immediately!
    Pull the trigger, you won’t be disappointed.
