Well, my car has had the superceded ST plugs since whenever Ford changed to them & my car gets better mpg & runs just as before, so am happy with them. One thing to point out is my car is standard.

yeah but 170 quid is a lot of money for five plugs Gaz 😂

my above post (edited) might have sounded like a dig at the ST plugs but I was thinking more about a discussion on the forum about the plugs a while ago, I think people were disappointed about the original rs plugs going obsolete as it were 😉

Agreed £170 is shocking!

Knew what you were getting at Jim.

If people already have plugs they've bought, put them in yourselves, it's really not rocket science to do!

It may be a placebo effect but my car seems to run better on cold start but defo 5 mpg better, I wouldn't go back to the original plug personally & whatever people think of Ford, they wouldn't say the ST plug is suitable if it wasn't, they sort of know what they're doing! 😁 (can't say the same some dealers)! 😂
