*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.

billet intake manifold plenums
Instructions was a bit confusing. The instructions had tapered screws; these were allen heads with a shoulder. When I opened one bag of screws the allens were diffrent sizes from the second bag. The screw was the same size but the allen head was a diffrent size and the shoulder of the bolt was larger the torque specs were all the same. nobody can see them anyway. The plenums fit great heavy duty and look great to bad no one can see them.

A work of art
I got the 2 inch plenums because I have an OBS 1997 Powerstroke. These things really are a work of art. They are very sturdy and well made, it gives me confidence knowing that these won't lift or leak when I throw boost to my engine. Thank you Clay for making the 2 inch ones for the OBS trucks, I am very happy with these.

Billet Intakes
I happen to be a machinist with 43 years in the trade. I have to say....These. Are. Beautiful.
The step over on some of the surfaces only add to the beauty.
I think the oring groove could use a few pinch points to hold the oring while installing...minor thing though. -
Looks good, fits good
Definitely buying these for my other 7.3's. They fit perfect and I love the way they look. It's a shame they're under so many lines and wiring.

Billet Plenums
These are a piece of art and I wish they were not buried in the valley. Extremely well made, no defects. Took me some tries to get the rubber ring on, but once on, extremely resistant. Installed same time as a T4 S363 kit and new single shots. 2000 Excursion. Runs extremely strong with 300k on it.
