What material is that? Looks great the way it is... That is the basic design I tried to make in the past, but never quite pulled it off that nicely. I had hogged out the mouth of the intake and tried to taper the adapter hole for a bigger throttle body.

It's MJF Nylon 12 from Xometry (or other online places). From a real expensive HP printer

. But a piece this size is about $30. A fair cost to get a prototype before I send it to get machined in Aluminum. Matching the opening all the way through from intake to throttle body. As we all know the factory unit necks down almost 10mm less than the opening.

I'd be tempted to run that piece and see how it does....

It looks nice. Would it clear the larger than K26 turbos?

I'm putting in a Voodoo turbo, so we'll see. If it doesn't, I'll modify the CAD and make a new one.
