I wouldn't use these in a tuned car. You should use the Ford AGP 071 plugs, cheap as chips and good for 200 to 600bhp .

are these plugs likely to cause damage if there left in for a week or so then mate?

Not in normal driving, just don't hold any high boost.

As above unless you want to spend more on a plug with more longevity and better cold/slow running, in which case, the Denso iridiums are unvbeatable.

I used BCR8ES plugs in my first Cossie and it used to melt / blow the end off one about every other time I drove the damn thing (usually no.3 cylinder IIRC). Not sure molten spark plug tips would have done the pistons much good either, but I didn't know much about Cossie's back then and just kept changing them !
