These are the engine bay intake hoses for the MK1B AW11 MR2 NA. I am currently successfully using the throttle body hose with no issues out of TPU(1600 miles) sub freezing temps and over 95 degree summer days with hard driving.
I also have a phenolic gasket, so the intake does not get hot, although I'm sure the TPU can handle it. I also moved the vacuum port location on this hose a bit to better suit my custom idle up valve solution.
The corrugated hose is still being tested, this is a pretty hard print, I am trying PETG for this, although a TPU would work if there is an easy way to support it. The seal should be a pretty good fit. The PRE afm pipe probably needs more angle work. I am still working on these.
