Ignition coil DELPHI or OEM Volkswagen

Just did my 2016 Passat SE with Delphi coils in June. Running smooth.

the Delphi coils are what I've installed most recently, and I have the most confidence in them being reliable.

AC Delco is an OEM GM parts and any coil will do pretty much personally I use Delphi ones they seem to last pretty long

I got Delphi and they work great

Delphi. I'm confident they're better than Bosch.

You can use either, but Delphi is OE.

NGK plugs and Delphi coils. Do not get Bosch

Honestly it just sounds like a bad coil on 1.

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.

I tested the coil and found it to be faulty (that's what I get for buying a cheap one). The first time I tested it, it seemed to be fine but that was on the truck. This time I took it off to make sure I got a good connection and sure enough it fell out of range on both of those tests....
