Share on social networks:
Acdelco is OE for GM and yes like everything it's been outsourced but I've never had issues with fitment or getting the wrong part from acdelco.
Pros: good fitment, correct part
I did a coil on plug conversion on my race car using just stock truck coils. They fire the methanol without issue even when it's rich enough to milk the oil
Pros: fire methanol without issue, handle rich conditions
My mazda coils were already on 20k miles or so and 1 coil developed some white stuff under the coil , so i grabbed AC Delco 585 coils , installed them and i think in general car runs better but the cold/hot start... With my mazda coils it would start in literally 1-2 seconds , now sometimes 4-5 seconds, it doesnt have dwell remap.
Pros: car runs better
Cons: slower cold/hot start
Vehicle:
Mazda
