Reviews of OEM Mazda ignition coil

Very dependable even with low boost, pretty simple and easy to work on. They are known to burn oil, and the coils fail pretty frequently, those are the worst problems I had with mine.

Just OEM's replaced on time, car runs like a champ and sees track days regularly

I replaced the ignition coils and spark plugs given their age / mileage and online recommendations around the weak Mazda coils. Honestly, I didn’t notice too many changes but again, piece of mind.
