Ignition coil Bosch or DELPHI

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.....
