I received the aluminum MAF delete/IAT tube adapter from BEGi and, while the depth was accurate, the sensor did not thread. I called customer service and they explained it probably got warped during the welding process. They offered to send me a new one, but I had access to a machine shop to re-thread it so that wasn't necessary. They put a credit on the account instead. For the price, it did seem a little flimsy so I can't give it a strong recommendation:

tl;dr: Part was defective and thinner than expected. 2/5 stars. Bell Customer service > quality control

Sounds like BEGi wins again.

If a person was gonna DIY something like the BEGI part, is any one metal better than another--aluminum, mild steel, stainless, etc? Heck, even PVC?

Whatever you feel comfortable working with, provided it won't melt.

One time I needed a quick fix for an IAT mount so I epoxied (probably JBWeld) a 3/8NPT weld bung into a straight section of 2.5" OD aluminum tube. I scuffed the hell out of the surfaces and used a generous amount of epoxy and it held up fine. Sure it looked like *** but it worked! I wouldn't recommend this for a long term solution, but I'm sure you get the idea. I replaced it with a unit of similar construction, only welded instead of epoxy.

I can inform that my 3D-printed part is still holding up just fine after 3 months now. No deformation.

Not sure about PVC, since it is pretty close to the exhaust manifold, but the OEM toobs are plastic and they don't melt (although they could be some kind of heat-resistant polymer). But using the same reasoning, I figure any metal should be OK. I just can't bring myself to pay $35+s/h for something like the BEGI part that I think could easily be DIYed for $15 in materials.

Try scaling it down 10 times. Length should be 120mm.

Sorry about that. I always model in 10 or 100:1 because Sketchup is stupid with small measurements.
