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.
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
Get a Bosch and skip the brand logo. Same part and available…aaand cheaper. Same issue for me c63s.
Bosch working great for a few years now, cheap as dirt on rockauto
I bought the Bosch 4 yr and 10k miles ago and haven't had issues.
I've switched from standard to the Bosch ones last summer and it significantly improved the acceleration on my 124 Abarth. Prior to the switch I'd see lots of misfires and "bumps" in the power delivery curve. The Bosch set was not a hard sale with being under 280€/260$ here in CZ. Highly recommended for anyone with power mods.
I replaced my coil around the same time, and no start failures for me either.
This is a new Bosch coil (but also happened with old coil), wires, cap, rotor, and plugs as mentioned above.
I have changed the ignition coils, spark plugs, MAP sensor, fuel filter, and ran fuel cleaner in the tank twice. The only time it seemed better was for a couple of months after I changed ignition coils (Bosch).
Just replaced my coils. AVOID Bosch. Literal trash that does not even work.
