Ignition coil Bosch or OEM Volkswagen

Changed the plugs, and while changing them noticed that there was a little charring in two of the coil paks seating surface where the spark plug tip sits...after changing the plugs the car still felt like ****. Ran to Advanced....and they showed 2 cylinders not firing good, needless to say they only stocked one coil pak. I replaced it and the car ran like a champ.

had the same problem in the gti...just got a replacement coil pack for 32$ at the VW dealer and was good to go...i hear its a common thing to replace...

I ended up getting a brand new Bosch ignition coil from German Autoparts for around $160 shipped with a few other small parts. This was around November last year.

Go Bosch, or Go Badly.

0,5l/100km less fuel consumption, consistent, and what is most important, my Golf was the only car that started by itself this winter at -30 C outside, among about 30 cars in our courtyard.

I highly recommend this one: It gives probably the hottest spark out there, is a direct replacement to oem coil and is not expensive (~$30).

It's Bosch KS with a turbo 5K coil. The turbo coil is known to work very well for 18+ PSI, and I am firing it earlier in the cycle than most, which should make the job of sparking easier.

Get the Bosch Blue coil either way though.....

Performance gains from only a coil, I don't know, probably none, however the car I have it in is completely stock in the engine department. As an addition to mods I think the coil is a good idea because it helps to smooth out these cases when mixture is out of stoich Maybe better throttle response.
