Car appreciation... the aesthetics, the engineering, etc

I had multipoint plugs in my M3 once and had to remove them. Absolute shit.

The R32 had multipoint plugs and when they were removed the tips were black.

I'll never use them again - platinum all the way from here on in.

How about iridium ;)

I've not had a problem, but then only ever used the bosch ones. Am awaiting a set of 4 electrode platinum ones for the beemer when I service it, may even change the cambelt too.

Flip side recently had new NGK plugs fail, out of the box. Just one in a set of four.
