Ignition coil DELPHI or Denso

Yes Denso Oem, good as originals.

I've used denso and Delphi. They are oem suppliers to ford. I use them interchangeably without issue. Not sure about other brands. I do know that many have had poor results with the cheaper brands.

I got Denso ignition coils for my honda s2000 using the matching OEM part number. they were real. don't buy off brand, especially if it's a performance car

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

I had a bad coil that only misfired when the car heat soaked after a drive. If I didn't let the engine cool down a bit, it would misfire on startup. I found one of the coils had a rust spot on it, replaced it with an OEM Denso and have been running for almost 4 years with no problems.

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 bought a new Denso coil to put on cylinder 3 just to eliminate it as a possibility.

NGK plugs and Delphi coils. Do not get Bosch

They don’t look like OE plus they have Delphi stamped on them. I’m pretty sure Delphi is not an OEM for BMW. The tarnishing looks like rust which could be explained by the use of inferior materials.
