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).
Pros: work great, solved misfire issue
Vehicle:
Jeep Renegade
Mileage: 128747 km
Just OEM's replaced on time, car runs like a champ and sees track days regularly
Pros: runs like champ, sees track days

I replaced the OEM coil with an MSD ignition coil earlier this year after having similar misfiring issues. Haven’t had any issues since.
Pros: no issues since
Vehicle:
Chevrolet Sonic
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.
Pros: solved random miss, pleased, added pep

I’ve never had an issue with my Bremi coils. Just replaced the suppression tubes. M50/M52 coils very rarely fail. Just the tubes.
Pros: no issues, reliable
Vehicle:
BMW
I ran this on my AP1 and it worked greats
Pros: great performance
Vehicle:
Honda S2000
Part number: GN10370
I replaced the ignition coils and spark plugs given their age / mileage and online recommendations around the weak Mazda coils. Honestly, I didn’t notice too many changes but again, piece of mind.
Pros: peace of mind
Cons: no noticeable changes
Vehicle:
Mazda
But, its Bosch ignition coils had a defect and were being recalled.
Pros: defect, being recalled
Vehicle:

Don't bother with the R8 coils that everyone says is an upgrade. It isn't. They are just red.
Cons: not an upgrade, cosmetic only
