Ignition coil Bosch or MSD

I ended up going with Bosch and haven’t had any issues.

Just stuck a load of Bosch in mine, worked a treat, xHP throttle blip downshifts were sometimes jerky and causing transmission faults but now they’re as smooth as butt’uh.

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 bought four of these from the Audi dealership and slapped them into my MK5 GTI when I replaced the spark plugs. They work but they aren’t any performance upgrade. I got ‘em because the car is also red ????

Coils: buy Bosch or Delphi coils. DO NOT BUY THEM OFF OF AMAZON. You would be better off leaving them then replacing them with an aftermarket brand.

I had all new Bosch coils installed on my e46 M3 about 30k miles ago. They worked fine, until one day the car went into limp mode due to bad coil / misfire.
