*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.

Craftsmanship
Another high quality product. Due to weak sheet metal design of the factory pieces that leak with increased psi, these plenums fix all those issues. Quality billet, cnc designed with an oring and increased thickness eliminating all weakness and potential failure points. Seeing 30 plus psi and pressure tested with no leaks.

Billet Plenum Kit
I was hesitant of installing the orings after reading some of the reviews, but it was not an issue. I guess it depends on experience but it wasn't an issue. Far better than factory, and fit perfect on my 1996 7.3 truck. Great addition to my intercooler install., and I recommend them for anyone that is tired of the leaky stock plenum.

Well made in the USA
Much better quality than my stock parts. It was a little difficult getting the o-rings on, however in my opinion better than silly RTV.

Billet Plenum Kit
This is a much needed upgrade over the stock intake plenum. Overall straight forward install, just follow the provided instructions. Make sure the head surface is clean, and if you are in a cold climate like me stretch the oring before install and they will drop right in. Stainless hardware is a very nice touch as well.

OBS fittment
Nice finish, O ring is a pain to install on plenum, dosnt like to stay put. Would work better if it was form fitted. The biggest problem is on the passenger side head. It is not beveled for the fuel line fitting to attach to fuel line return to bowl, and the bottom bolt that is slotted dosnt come out far enough to get plenum in without rolling little o ring gasket. Had to dremel spot for fuel fitting and cut down spot for bottom bolt to fit without rolling gasket.

Billet Intake Plenums
Great upgrade over my stock plenums. The machining and design on these are unmatched. Oring seal is a great design over the ford rtv. Instrcutions are well written and took all the guess work out of install.

Billet Plenum
I was a little worried by a couple previous comments on the oring install, but honestly it isnt hard at all. If you have any experience at all and follow the directions install is straight forward. Recommend these 10/10, and Riffraff was very helpful with any questions.

Billet Plenum Kit
Excellent upgrade over the cheap stock ones. So nice to get away from the rtv and move to a real oring seal. The green is the perfect accent to my engine bay.
