Ahmotorsport Posted April 6, 2011 Share Posted April 6, 2011 What are good sparkplugs to use in my 2.0 silvertop?I think I read somewhere that focus RS plugs are ok to use.We use Focus RS ones in an ST170, not sure if they'd fit Silvertop, i presume so but don't go by that.

Stu Posted April 6, 2011 Share Posted April 6, 2011 Standard plugs from the Fords parts counter are the correct plugs to use. Link to comment Share on other sites More sharing options...

Stu Posted April 6, 2011 Share Posted April 6, 2011 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. Link to comment Share on other sites More sharing options...

Stu Posted April 6, 2011 Share Posted April 6, 2011 Whatever you do, don't use Focus RS plugs unless you know what you're doing. Link to comment Share on other sites More sharing options...
andrewsalter Posted April 6, 2011 Author Share Posted April 6, 2011 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.

Stu Posted April 6, 2011 Share Posted April 6, 2011 I'd ignore what forumites say and do what Ford recommend. They know best. Link to comment Share on other sites More sharing options...

sidrick Posted April 6, 2011 Share Posted April 6, 2011 Running plugs from a 200+ BHP tubo motor on a 130 BHP NA car would be an odd decision. Link to comment Share on other sites More sharing options...
