What brand is the best replacement? Probably going to have to replace mine for the 4th time and i want it to be the last!!! HAs anyone had problems out of an msd box burning up their opti's? The original cap i replaced when the water pump went, then the 2nd cap went when the coil lead burned through the front of it, 3rd was the accel cap that was bad out of the box, now i think the accel optispark has gone bad after about 100 miles. Thinking GMPP because i didn't really have trouble out of the first one, just swaped it for preventative maint. and have caused alot more maint. i am afraid. Anyway does anyone else have a msd box on their opispark???
