Guys,
I've got a set of WR78 Bosch super4's from my 320 which are brand new. I'm assuming they're all good for the 2.7 application?
Cheers!

Its been discussed on here loads, there was even a thread of a couple pages and most people recommend NGK BPR6ES plugs. Most people with 2.7s including myself use these plugs
E30 Crazy!
Nothing wrong with Bosch plugs at all - even the basic single electrode ones work well in such an old fashioned engine. Don't forget thoughn that thge higher the compression, the hotter the combustion so you'll need plugs to suit.
The NGK BPR6ES is a good plug, as is the Bosch W7DCR. I can't find an NGK cross reference for the WR78, but if it's a Bosch heat range 7, it'll be up to the job.
