Around 2 months ago, one of the starting coils failed. I checked here and some said that the stock "Delphi" coils are known for failing. So i changed all of them for "Bosch" coils.
Cons: stock Delphi coils failing

Hitachi IGC0003 from Rock auto, 3 years, zero issues.
Pros: zero issues, 3 years

I had issues with misfires until I replaced the coils with genuine oem. Before that I had all new Delphi 10571 which were not the same and ultimately fixed my misfire issues.
Pros: fixed misfire issues
Cons: Delphi coils not the same
Part number: 10571
get the Bosch brand their the same as OEM trust me I know don’t get any other brand even though their going to be cheaper get the Bosch. Besides honestly most of the ignition coils is Bosch companies just throw their name on it to charge more
Pros: same as OEM, reliable brand
Vehicle:
BMW
Get a Bosch and skip the brand logo. Same part and available…aaand cheaper. Same issue for me c63s.
Pros: same as OEM, available, cheaper
Acdelco is OE for GM and yes like everything it's been outsourced but I've never had issues with fitment or getting the wrong part from acdelco.
Pros: good fitment, correct part
Bosch working great for a few years now, cheap as dirt on rockauto

The Delphi coils are junk. Bosch updated the coils they offered and we've used the updated coil multiple times and never had to warranty a single one out in the 4 years we've been installing them.
Everytime we've used a Delphi in the past the white silicone on the boot degrades and falls apart in 6-12 months and customer cars came back with misfires again.
The old Bosch coils wear out because people don't do spark plugs and replacements on time. The old plugs end up with crazy gaps and it kills the coils. Usually at 100k-120k miles but honestly that's the normal lifespan of a pencil style coil regardless.
If you're plugs are old and you're beginning to experience misfires then save yourself the time do all 6 plugs and coils. Your N52 will thank you.
Pros: reliable, long lasting
Cons: silicone degrades, short lifespan
Mileage: 120000 km
I have used the MSD ones before but they will fail much faster.
Cons: fail much faster

APR coils lasted almost a year (5/6000 miles) when I pushed it and let go of the pedal. CEL would flash and random cylinders misfire.
Cons: short lifespan, misfires, CEL flashes
Vehicle:
Volkswagen Golf
Mileage: 6000 km
