Has anyone fitted one of these to their C4 ? I have just replaced my original optispark with one, and am curious about the performance of the part ? What effect does advancing or retarding the timing have on the engine/running of the car ? I have left it at the factory setting.
Oh and what other parts or brands are people using to replace their optispark when the water pump eventually kills it ? Thanks in advance.
