Reviews of AC DELCO ignition coil

I bought some AC Delco coils (just coils) for about $120 over a year ago (January 2025) on eBay, and my '07 Chevy has been fine so far.

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.

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

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.
