...however, my 2006 Boxster S, was an early production model...I purchased one that was on the lot, and was tired (no pun intended) and bought a model on the lot which suited my desired colors/options to all extent except for the one I overlooked....NO TPMS system, on top of the lack of a spare tire. So therefore, I...unlike all the other fools (that's sarcasm, as I was/am the fool) I needn't worry about tire glue on the sensors. In my relaxed state of mind, I think I'll do some reading about something I heard about....something relating to "IMS"....and don't tell me that I don't have to worry about it because my car is a 2006. It was a very early 2006, I believe it has the 2005 engine in it, (280 HP, no variorum)....let's just say...I should have bought that Mercedes C55 AMG....in retrospect.
