*Note: Factory 1994 - Early 1999 have 2" plenums, and Late 1999-2003 have 3" Plenums
*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. Due to variations in fuel systems, aftermarket HPOP, and turbos we can not guarantee fit with all options on the market. Some early OBS trucks stock fuel line adapters can interfere with the plenums. We suggest the RDP-FFL line kit in place of the stock fuel lines for the 1999-2003 models.

Fantastic Quality
This are beefy, bolted right up, great directions. Solved my leaking intake issue, I couldn't have asked for more.

Strong & beautiful
The website pics don't do these pieces of artwork justice. They are amazing in person, the machining is top notch, and the oring is so much better than RTV. Even stainless steel hardware and billet standoffs for the brackets are first class. From start to finish these are head and shoulders above anything thing else on the market, period.

Very Good Fit
I recently installed an SXE472 in my truck and ever since, the CAC to Turbo alignment had been off. When I received the RiffRaff billet Plenums, I noticed that they were slightly shorter than the OEM plenums, about 7/16" of an inch shorter. So, once I installed the billet plenums, it also allowed for further rotation of the 472 cover, and this in turn created for the proper alignment of the CAC pipe to Turbo fitment as well. The gasket didn't cooperate much either, so I also had to apply a slight bit of Superglue to keep the gasket in place. I used the glue very lightly, about every 2" or so.

RiffRaff Intake manifolds
These things look great. Solid construction and extremely easy to install. Only issue for me, is the only issue for everyone. That one stupid bolt!

Better than OEM
These things are heavy duty and perfect fit. The only thing I had an issue with was one of the oring gaskets wouldn't stay seated in the plenum and had to use a little hairspray to keep it seated while I installed it, but have drove a few thousand miles since then with 0 issues at all. holding boost perfectly.

Great, but
These plenums look great, perform perfectly, and are a great upgrade! Slight issues to keep in mind are the drivers rear feed line on the Irate RR interferes with the plenum and it must be ground down to clear. Only had to remove about an 1/8" and should not affect the function. Also, the CNC fab HPOP lines have a fitting that must be installed and clocked correctly before installing the plenum. Neither are Clay's fault, so I won't deduct a star for them. Just make sure you do both of those things before torquing the Allen head bolts.

work of art
The pictures don't do them enough justice. These are amazing works of art and engineering. Perfect fit, and I love the oring, it is so superior to the silicone on the factory ones.

BILLET INTAKE, T500 HPOP
I just did a complete upgrade for my early 99 7.3. These billet intakes and the T500 were just what I needed to make sure that my 7.3 will continue to maintain its well deserved title, "the work horse."
