I have ordered throttle body boot twice and returned them… as they are smaller diameter than TB on the car… I looked the part number up on RealOEM. The BMW-13541703588 is what shows up for my 99 M Roadster… but it’s a 90* bend. Mine is like 75* bend and the lip at the TB has a 12mm larger diameter lip than those I have gotten… any suggestions appreciated.

I have resolved the boot issue, and elected to stick with ASC, but removed butterfly to prevent actuation throttle back. The ASC is larger diameter than stock TB, so seems the restriction is minimal with Valve removed. I wanted to keep dashlights and ABS function.
