    A work of art

    Posted by Dean on Mar 5th 2023

    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.

    The design and machining is quite amazing on these plenums. From the oring, to the stainless hardware, to the professional box that it comes in. 5 stars!

    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

    Posted by Adam on Feb 17th 2022

    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.
