Ignition coil DELPHI or NGK

Ngk has been much better in my experience

I've had success with NGK coils via Rock Auto on multiple vehicles.

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.

Got mine from Rock Auto and have no issues. I grabbed Delphi brand per recommendations from forum posts.

Used the mitsubishi one’s in my 2006 9-3 - no issues in over 7 years of use. Used these NGK in my 2011 9-5 (they were $2 more per coil but had a 3 year warranty) Different engine with OEM being Denso but the NGK have worked fine over the past year.

I just replaced the plugs and coil packs on my 2016 granted it’s the 2.4l engine but I purchased the Delphi coil packs and they seem to work great and solved my misfire issue (80k miles on the odometer).

I recently replaced using NGK. Solved my random miss holding at 5k. I'm pleased with them. Not lacking anything. It added some pep to my step, for sure.

NGK plugs and Delphi coils. Do not get Bosch

Avoid Amazon if possible. I got fake NGK ignition coils once. I wouldn\u2019t order any part that is easily counterfeited off Amazon. Also got crush washers that were supposedly OEM spec, but they were made with the flimsiest piece of shit ever. I could bend them between my fingers.

They’re made by Delphi but they are different internally than the Delphi gn10571 or whatever they are, in the aftermarket. I had misfire issues and strange electrical feedback with Delphi aftermarket.
