0.6mm, get a group a coil as it helps no end if you don't have one already.

we have a 90 4x4 saph

we use ford escort cosworth platinum plugs set at 0.7 with a gpA coil @22psi full stage 3 set up .

check old plugs for any bad signs of incorrect fueling

i.e have u had it set up lately as it may have gone out of tune

have ours checked every year

Default PLUGS

No I haven't had it set up yet,only purchased the car a few weeks ago.I want 2 get everything sorted out on the car first,once that is done I will be taking it for a tune and maybe a new chip aswell.So 0.6mm gap then or 0.7mm but that is for your stage 3.Thanks for your help.Lee.

Default PLUG GAPPING

Sorry just had a thought.I have a standard coil at present,will the gap still be 0.6mm or will it be larger due to not having a group a coil?

If they are PP8s i respectfully advise you to remove them and use a cooler plug.

Default COSSIE PLUGS

Stu,no they are Motorcraft 071 plugs and have been gapped at 0.67mm,I think 27 thou with a standard coil at present.
I have now got a new group a coil and once that is fitted should they be re gapped to 0.6mm?1992 4x4 sapphire cossie is the car we r talking about sorry I forgot 2 mention that.
Stu I spoke 2 u on the telephone a few days ago about going to a stage 2 and I asked u would the standard clutch and standard turbo be ok,I also asked would an RS500 intercooler be required.Stu u may remember as I'm from South Wales.
Stu,when I bring the car 2 u whether it be for a rechip of my current stage 1 or a stage 2 set up what plugs would u recommend for either stage bearing in mind I will be running my new group a coil then,also what plug gap would u use please?
Thankyou.Lee.

Plugs are fine up to 700bhp and 0.7mm is fine for stage 1. If it missfires youve got faults to fix.

What STU is trying to say is if you use pp8 in a stage three cossie you WILL melt the plugs with disastrous results.
071's are fine for stage three, there is a better plug fpr road use think they are R31(?) STU stocks these too.
