Ignition coil DELPHI or HUCO

Stepdad recommended replacing ignition coils, so I purchased a 4 pack of Delphi GN 10369 from amazon. Sure enough, we just replaced the coils, and boom, it ran good as new (to me).

I have a 2017 Forte with the regular manual transmission 2L non-GDI engine. At about 19,000 miles I started getting a strange sudden drop in RPM at random times (idle or on freeway). I would mostly notice the loss in power when it dropped and it would return to normal usually in less than five seconds. Never got any codes and car ran great 99.9% of the time.

As I approached 23,000 miles it got more frequent and finally threw a P0302 (Cyl 2 Misfire). I inspected spark plugs first. To no surprise they were in great condition. I swapped cylinder 2's ignition coil to cylinder 3, cleared the codes with my scanner, and the coders all cleared. About two days later I got a P0303 (Cyl 3 Misfire).

I ordered a Delphi ignition coil (GN10877) on Rockauto to replace the suspect ignition coil. Haven't experienced the issue since. Car also idles so well now that I can't feel it in steering wheel or hear it at idle.

I had no idea how bad that ignition coil was until it was replaced and was still shocked that it started failing at 19,000 miles.

I think the only difference is lifespan and reliability. I wouldn't cheap out on plug-on-coils because the budget companies don't take as much care with the wire insulation (apparently 2 different temperature ratings are acceptable, and the cheap companies use the lower temperature), coil material, or the epoxy that coats and insulates everything isn't as good or isn't applied as well.

I went with (6 of each) Delphi GN10168 coils & NGK 2262 spark plugs. $150 with 5% discount + shipping. I hope I made a wise decision.

I had the same deal, but none of the similar error codes. Verdict: it's probably your ignition coil. Overtime they crack SOOOOO SLIGHTLY that they let in moisture and you're boned. I snagged the Huco cheap one, been fixed ever since. I finally saw the cracks in the old one when I took it off and it was easy to change. I have a 1997 Golf GTI 2.0 8v

I got it. All good now. I swapped a Meyle coil (probably original right?) Out for or a used known good Huco. Knock at idle is GONE and she reves right up!

glad to hear its fixed i had just recieved and replaced my coil to day(mine was HUCO brand)! And the car fires right up now in rainy or wet weather.

it sounds like a problem im haveing with my ignition coil, i could be completely wrong though but anyways an easy way to test it is to start the car and mist the ignition coil with a spray bottle if the car shuts off u need a new one, i got one from germanautoparts.com for only $60 plus $10 shipping and i got it practically the next day.

Yep. The codes don't lie, the coil pack is bad. I swapped it into my wifes 04' and the CEL/ misfire was right there with it. The guy bought it somewhere local but doesn't have the receipt/ record, so he's out $175.
