Ignition coil DELPHI or MSD

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.

I use Delphi on my N20 which use the same coil as N52. No problem so far.

I got my coils on eBay and haven’t had any issues in 3 years and still going strong. They are delphi brands so those are pretty good too.

Bosch Delphi eldor they’re all the same you can’t really say one is better than the other. Some go bad early that’s just what it is. I personally went with Delphi (they’re quite a bit cheaper on eBay). But the lifetime return/replacement from fcp is pretty enticing.

Soooo many burnt up MSD ignition coils. We tried our best.

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....
