Better in what way?

 

Performance? Better than those crappy Bosch 4-electrode plugs. Noticeably different to anything else? Not likely.

 

Better in that you can say you've got XXX plugs in your car down the pub? Sure.

I have this thread on another forum and this is one reply I got.

 

The zetec plugs in general are pretty crap. They soot up too much due to the heat, the best thing to do is to get the hole drilled and threaded for the cosworth plugs as they can withstand the heat

 

Whatever you do, don't use Focus RS plugs unless you know what you're doing.
I don't really,thats why I was asking.Don't want to do something I don't know about and do damage to my engine.
