Ignition coil Bosch or APR

Be sure to use a genuine Bosch from a reputable source, or OE from the dealer. DO NOT use a Chinese one from a big-box auto parts store.

Make sure the new coil is a good Bosch, Beru, or OE unit, not parts-store brand junk. I've seen plenty of bad coils out of the box.

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.....

Worthless cause it doesn't have an internal pin.
