I'm going to change the spark plugs on my MPi this week what's the general opinion on best plugs to use?

Generally speaking, you cant go wrong with Bosch or NGK. I avoid Champions, back in the 80's there used to be a dud in every box of 10, though by now, surely they must have improved the consistency of their quality control ........and they probably have 10 duds in every box now!

I've never been a fan of champion plugs. My old lecturer wrote an article saying jag V12's wouldn't run on champion plugs correctly, they took him to court but he won proving they were rubbish. I settled for Bosch today.

I had problems with Champions in my V12 Jag too!

My lecturer was convinced the KV's dropped off at peak fuelling with champions and proved it he loved telling us that story every week bless him
