Cheers guys,
I thought some were running somthing other than standard, and was curious to know. But good to know stock items are being used. Indeed, when I asked a 7 Zetec specialist about it years ago his answer was: Ford have spent millions devloping the engine, their 'plugs are probably therefore the best to use.
Chris, I know you document your 7 well; if you have the NGK part no., would you let me have it please? I spoke to Chris at Raceline but he couldn't recall it off the top of his head; and the look-up book at Halfords leaves me doubtful I've bought the corrrect ones.
Here's an interesting, and worrying find. When I removed all the 'plugs today, they were all Motocraft but two were AYFS 22P1 and two were AYFS 22PG1. I've been running these for years ❗ Web searching brought up almost nothing for them. *confused*
cheers
