I read a few posts suggesting that the black Bosch ignition coils were more reliable than the silver versions.

I found a few websites with photos of the black version, although after an email they confirmed it was the silver version.

Has anyone recently purchased a new black Bosch ignition coil?

The ones I recently purchased from Pelican were silver.

There haven't been any black Bosch coils in several years since they switched production from Germany to Brazil.

If you have a silver one, my best advice is to carry a spare.

Thanks. Guess I'll go ahead with silver then.

What is the difference with these two bosch options? What is a C-Core?

"What is a C-Core?" It's the shape of the magnetic core inside the coil which the magnetic wire is wound around.

and i think i read a post from lorenfb that the 993 dual unit is compatible. presumably the unit above is the 993 dual unit?
