Will review once I get it installed. I would assume it is similar to the Bosch Blue coil. Should work well with my new Blue Streak points.
So visiting a VW forum there were some comparisons between the Pertronix and Bosch Blue. The readings on the Pertronix shows 35 kv cold and 28 kv warm. The Blue coils readings were 17 kv warm and anywhere between 15 & 9 kv warm. I don't know how much this is relevant, but those VW guys are serious about performance enhancements.
