What did they want extra for the Synchro Spark? I'm not sure I would agree with the no real advantage comment either. It gets rid of all that linkage that over time will develope slack. I put a Synchro Spark unit in my G62, and it has been one of the best things I have shed bucks for. I don't ever have to worry about the ignition timing. I wish my Fox 2.4 had it instead of the linkage, but then I only paid $400 for the Fox.
