Optispark O-rings
I was about to re-install my opti-spark and I noticed the two O-rings on the end of the shaft are just pieces.
Do these have to be dealer bought? The local autoparts places looked me like I was stupid to even ask for them.

I would replace them if I were you.
10474278 is the p/n for them at the dealer. I am not sure there is something special about them from a regular o-ring that you could get at a hardware store. From just feeling of them, they seem to be much sturdier and tougher than the common ones.
