I checked Cura and recommended print temp for TPU is 228C. I bet it would last a while before you had issues.

neither, I'm an idiot. I use the Cura 228 Spork posted. Not sure where I got 270. PETG prints around 250F. That's the hottest filaments I've used.

There is a lot of random stuff for TPU on the interweb... Let's just say, it's all very confusing with TPU because the "Glass Transition Temp" (GTT) is less than freezing but I haven't been able to find a specific temp that it looses it's elticity. However I have found a temperature range that it can preform at which is also widely disputed, -40 to 120°C. For those of us that like Fahrenheit that's -40 to 248°F.
Now this is where things get fun. Reading from several car forums, tube headers run at a temp anywhere from 350 - 700°F depending on rpm and such. Which is far above TPU's operating range. The reason that tube header temp is important is because the air inlet tube is right above those headers..... TPU melts at around 437°F. Now if I knew the air temp on the bottom of the air inlet tube after he does a drag run, I'd know really quickly if this is feasible. I've thought of trying to print some sort of heat shielding out of ASA and some trapped air, then using TPU as more of gasket but I don't think I'd be able to replicate the look very well with that method.

You could use a digital meat thermometer to take some readings. There are some starting around $10 on Amazon.
There are wireless ones too, if you want to get fancy.Or just print some TPU and stick it under there, and see how it is affected before printing a large thing.

How many smiles per mile? (At 10.23 MPG)

Driving up there were a lot of smiles. Cool air, engine rumbling noises, little traffic and lots of open space in front of you. I had a bug hit my windshield just before Smith and Edward's so I bailed to 89. That was very pleasant, almost cold at times.
Drive back kind of sucked once we got into Ogden. Traffic backed up to 84 ramp from Roy, 90* temps. Still fun that the car got home without a trailer

Pussy. 😄. I maybe had a dozen Willard bugs, most being on the curbside front fender, first time it's been on the I-15 though.

When my wife and I were dating, her sister's cat kept walking on her new truck. My wife warned her... Fortunately for the cat, my wife couldn't make the duct tape stick to the driveway behind her tire. I try to keep that in mind when she warns me.😬

Any other methods people know to find an electrical draw other than multimeter on the battery while you pull a fuse and check to see if the multimeter quits going down? I always break those cute little glass fuses.

With an accurate meter, you can even check both sides of a fuse with it still in to see what the voltage drop is. There are charts out there that tell you how many milliamps of draw you are getting based on the fuse rating and the voltage drop over the legs.
