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.

*Will not fit 94-Early 99 with stock style turbo. 94-96 have 8 mounting bolts, and 97-03 have 10 mounting bolts. Make sure you check to make sure you have selected the correct ones. Provision for the AIH ground, and passenger side fuel line clamp has not been made in this kit as normally they have already been deleted.

  5. These! These! These! 5 Star Review

    Posted by on Mar 18th 2018

    This is the way a plenum should be made. No RTV and hope it doesn't blow out like mine did. I purchased a set of welded ones with my T4 kit and had nothing but issue. Boots wouldn't stay on, RTV blowing out. The quality and engineering Riffraff has put into these shows. Not to mention the great custom hardware and spacers that came with it. Home run!

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

  9. 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!
