Owner reviews for ignition coil

That's the Delphi coil. It's the updated part from the original all black Bosch. It's the only one I put in my customer's cars.

Delphi is considered the go-to for N52 coils.

I've been running the NGK since I'm pretty sure they are the OE manufacturer. Subaru is charging crack prices for those coils.

Just happened the other day with my 2015 Corolla. The CEL and the Trac Off lights stayed on. Turned out to be a bad ignition coil. Easy fix.

For me it was just a bad if ignition coil, replaced all of them myself and it was magically gone afterwards!

My delphi has been running good for about 20k miles with ngk wires and plugs.

Bosch WERE awful when first introduced, but lifted their game.

Had ignition coils & AC/Radiator fan unit replaced aside from regular maintenance.

I don’t like the Delphi ones cause they come apart, if you do spark plugs again say 20k miles passes you could deal with the silicone tube on the end getting stuck down when pulling them, then you gotta be careful and get the spring and that out without the spring flying off somewhere.

The auto shop found out what the problem was as they had replaced two of the ignition coils with OEM and two from a company that produced the ignition coils for Mazda. The two from the company (Delphi) went bad. I have to use only parts from Mazda.
