*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.

Amazing American made Quality!
I can't believe how amazing the workmanship is on the billet plenums. The pictures don't do them justice. From the well thought out oring design to being extremely robust in build. Unlike so many other products I have seen or installed, you can tell these guys are doing more than just stamping out parts to sell, they seem to really care about our little PSD community. Thank you for providing great USA made products for us Riffraff Diesel. FRx will be my next purchase without hesitation after seeing these.

Awesome Plenums
I bought these for my 7.3, and the fitment is great. One thing to take inconsideration though is the thickness compared to stock one. I am running a regulated return that feeds through the rear test ports of the heads, and because of the thickness difference I had to add a nipple to raise the AN fitting up a little. Not a big deal, and really like these plenums!

New Design
I ordered these before I knew they were redesigned. They are very nicely machined, and the anodizing is very crisp. I have not had a chance to actually mount them up (motor is out being rebuilt), however visually they are beautiful. I also opted to ask Clay about custom color (orange) which came out awesome.

Worked perfectly
Very sturdy design. The o-ring is handy because RTV is messy and can be a chore to redo.

Incredible
Read the rest of these reviews, they are all saying the same thing. These things fit great, are machined really well, and no more RTV.
