It's a solid piece and there is no issue removing it multiple times. The beauty of servicing the S54 is the full intake system is easy to remove compared to other BMWs. I wouldn't replace a thing under it. Maybe you can swap the TPS if the one near the oil filter is newer than the one on the throttle actuator.

Curious, but what did you go with for boots and clamps? I bought the turner silicon ones, then returned them and ordered the OE boots and clamps...

That makes sense...main reason I was thinking about some of these components under plenum is I'm mapping out what items I should replace when doing the Karb box. Mainly because I don't want to remove and install the plenum a bunch of times.

How resilient is the Karb plenum? Mainly connection points and the little cable holder near the firewall?

Part of me wants to replace everything under the plenum so I don't have to remove it frequently and possibly break things when doing so. Is this an irrational thought process?

Glad they seem to be fairly reliable as I haven't found many threads on people having issues online. It's pretty scary as I noticed it's pretty expensive through FCP, but a little bit cheaper through Schmiedmann.

My guess is the S65/85 are more prone to failure due to their location inside the V of the engine where things can get pretty hot. Either that or the internal components are different from the S54 throttle actuator. For the S54, I would not hesitate to replace with a used, good working unit since they are pretty reliable and easy to access.

Wondered about this as well, you hear about it often on E9x M3's/E6x M5/6's.
