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.

 

Hey there - for some reason, shapeways is not happy with the dimensions of this STL. Could you list them real quick for me? 2.75" od? 2.5" id? What length? Thanks!

 

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.

 

I hate to resurrect a dead thread, but it seems as if the thingiverse link has either somehow changed or the “thing” is gone. I’d doubt you’d still have the file by chance, but if you do, I’d be interested in a copy

 

A simple search of "miata iat" on thingverse and I found this: https://www.thingiverse.com/thing:5322754

 

Yep, that's the one I shared. It worked pretty well but heat soaked like mad. But that's honestly to be expected given it's location and plastics poor ability to dissipate heat.

It was a decent temporary solution as I learned the ECU before I went turbo.
