Can't help with what grade etc - But I do know that the jp4 engines use different size plugs to a normal j4.

You probably already know this.. But I don't know if you have the engine there or not, so just incase you was buying for when it comes. :y:

Im not at home right now so can't tell you the exact model I use, but as pointed out j4 and jp4 differ. J4 plugs do not protrude past the head enough (jp4 plugs are longer). If you don't have a reply by tonight when I'm back home I'll dig out some part numbers for you. :)

the fiesta and escort rs turbo ones are two diff lengths...one is ok for the 8v/j4 (cant remeber which)

the other may be ok for the jp4 if they need longer?bes off checking ho much longer you need though

I could be wrong but irc I thought Evo plugs were good to go?

rs turbo plugs are what i was using in the j4 head.

Ads sorry mate, completely forgot. Now on iPad. I do run evo plugs, (evo x). Heat range 8 for me - NGK R2556B. You may not need 8's tho which brings the cost down. Try standard evo x plugs and see how you get on.
