*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.

Since we're in there
The new plenums were ordered after I pulled the turbo out and was doing other work. Fast shipping, helpful advice and the most beautiful billet work I have seen in a long time. That coupled with a very reasonable price means you cannot go wrong. The hardest part of the manifold change was which color to pick. We are breathing life back into our 450,000 mile unit. Thank you Clay and Crew.

Top Notch Billet Plenums
I decided to purchase these plenums since I was tearing apart the top of the motor to do a bunch of upgrades. These plenums are very high quality and having them with the Viton O rings makes them super nice. Comparing them side by side with the stock plenums you can see they have much better air flow. Do yourself a favor if your also installing the fuel rail cross over at the same time, once the stock plenum is off and before installing the billet plenums remove the 2 fuel plugs on the heads for the crossover. Its much easier at this time while the plenums are removed.

American Made Excellence!
You won't find a nicer made set of plenums from anyone. I got a set of blue and I can't believe how great the machining is and the color. I would recommend anyone to purchase these, better flow and much better seal.

Nice part looks good
Be weary though they no longer come with studs as instructions indicate and it only comes with enough hardware to mount the relays not your fuel line or your ground wire . Other than that they seem fine .

Best product on the market
It's the best product on the market! Built better than the others out there
I run them on 3 of my truck -
engine swap
I ordered these plenums in black. Have a used engine i'm putting in the truck. Installed these pretty fast with some basic hand tools. Used a vacuum with a scraper to get out all the old grey sealant. To me they are worth the money. I think about every time I turn that key, I can rely on my truck to get me home.

Had to replace old plenums
Doing a bit of work on truck, which include replacing turbo etc, while I ordering parts, I first started off by buy the Re-enforcing sleeves, little did I know for some reason had early plenums on a late 99 truck, anyway after a call to HQ I had ordered a set of the billet plenums. Shame they are hidden away under all the plumbing and wires, so far so good
