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.
R8 coil packs definitely work better IF you’re tuned.
I replaced my coil around the same time, and no start failures for me either.
I gave the Jetta back to my son last week after replacing the coil. No issues yet - but mine was happening less frequently.
Been over a week with the new coil installed. No failures.
I believe Delphi is what people switched over to because the Bosch coils were failing.
This is a new Bosch coil (but also happened with old coil), wires, cap, rotor, and plugs as mentioned above.
Don't bother with the R8 coils that everyone says is an upgrade. It isn't. They are just red.
