Can someone tell me what gap I need on a set of motorcraft plugs on a stage 3 Escos?

Cheers

 

Anyone

 

standard it would be:

LT 0.8
ST 1.0

dont know if they would change for bigger power, wouldnt thinks so.

 

i run a 0.5 to 0.6 gap mate,

 

GGR recommends setting it to 0.70 mm

 

well i have group a coil and 909 leads and i just get a miss fire above 0.6

 

u using group a coil and still can't increase the gap? I'm just using the normal coil and I set mine to 0.7mm and everything is sweet, but I'm using champion's racing plugs

 

i run 23psi and gp a coil, and im running .85mm,better idle quality too

 

thinking of either do a coil pack conversion or just replacing the coil with a group a item (a lot cheaper). any benefits in using the group a coil? how come it is cheaper than the standard coil? anyone know?

 

go coilpack - you will never have a missfire again !!

 

400quid and 40quid, which one do u think the missus is going to pick? we are not talking about handbags!

 

lol,i paid £25 for mine,brand new,good old ebay,lol

Plug gaps will defo have to be made smaller if running seriously increased boost, IF it starts to BLOW SPARK OUT, ie prevent it from sparking the HIGHER the PRESSURE in the cylinder, ie BOOST or CR the higher the voltage needed to jump gap at plug.

bearing in mind that I actually live on the other side of the Earth, I don't think Matt can do £32 delivered, if he can, I'll take one right now

 

Sorry did not realise you lived somewhere sunny, not used to sun living here!!

I just changed my plugs and the car drives spot on untill you bring in full boost then it missfires like a pig..

Make the gap smaller then?

 

I've set mine to 0.7 and there spot on

 

When my car had(new) 909 leads it missfired under load with standard coil at 0.6mm, change leads to MAGNECOR missfire went away, now got group A coil so going to gap larger.
