Riffraff Diesel Billet Intake Manifold Plenums for Ford 7.3L 94-03

Our Gen 2 billet aluminum intake manifold plenums are 100% made in the USA from USA materials.

An engineered design that addresses several issues at once: 

- Pair of 6061 Billet Aluminum Plenums - No more sheet metal to bend
- Made In the USA!
- Anodized Black and available in custom colors upon request
- Larger intake mouth to accomodate flow
- Countersunk mounting hardware for seamless install
- Viton O-ring seal rather than RTV - Tested at over 100psi
- Works with both dual and single HPOP's
- Billet spacers for GPR and GPCM brackets
- Plenum mouth O.D. is machined to retain intake "Y" better for T4 style kits

If you are looking for a true billet solution at an economical price, then this is your product.

  1. Worth every penny 4 Star Review

    Posted by on Dec 28th 2017

    I would definitely recommend installing these if your ever replacing turbo or pedistal. Easy to install I love all there products.

  2. Billlet 3" Plenums 5 Star Review

    Posted by on Dec 10th 2017

    Really dig the look but the seal you get from these plenums is hands down....THE BEST!!

  3. SO NICE! 5 Star Review

    Posted by on Dec 1st 2017

    Such a clean addition to my build! No more messy RTV. I should have put them on when I changed from E99 plenums to the larger a long time ago!
    Some notes: being an e99 I needed one extra short screw because the GPR mount is different. Clay just sent it (thank you thank you thank you)
    I did some custom boss-JIC fittings for my HPOP lines and 1/8" NPT-JIC for fuel return that could not be installed (safely) while the drivers side was on. Easy peasy hence the lack of RTV!
    My old lady's excursion is gonna get a set soon!

  5. Great product 5 Star Review

    Posted by on Sep 27th 2017

    These plenums are great compared to the very thin stock plenums. 10/10 would recommend these.

  6. Top quality finish 5 Star Review

    Posted by on Sep 26th 2017

    These are far superior than the stock plenums
    The finish is top quality also
    Arrived in Australia with no damage and good time
    Will definitely be buying from RiffRaff again

  7. Quality far surpasses stock 5 Star Review

    Posted by on Jul 7th 2017

    I was surprised to see how flimsy the stock plenums are, no wonder they leak! The fit perfectly and are very high-quality. If you have the turbo off, I would highly recommend replacing these while in there. The O-rings are such an upgrade compared to screwing around with messy RTV.

  8. Awsome product 5 Star Review

    Posted by on Mar 9th 2017

    Installed my plenums at the same time I done the evbp delete which is the best time do it all at the same time I also done the banjo bolts,cvd fittings & the boot & new clamp along with the pedestal bolt kit & turbo install kit

  9. Great Quality 5 Star Review

    Posted by on Mar 1st 2017

    Did this job at the same time as a Turbo/EBV pedestal delete, pretty straight forward once everything is removed. I ended up just removing the fuel bowl for extra room. Used a Dremel with a cut off wheel to remove the passenger side plenum bolt that hits the HPOP and can't be backed out. Really happy with the quality of all Riffraff products.

  10. Riffraff products are the best 5 Star Review

    Posted by on Oct 12th 2016

    The quality of these plenums is excellent. I've ordered several parts from here and everyone has impressed me. If you need injector cups don't even hesitate to rent the installation tool ease of use and quality of tool makes this job so much easier
