Hello, what spark gap is the corret with a WEBER MARELLI group A coil, stage 3 engine and DENSO PP8 sparks???

 

I assume from your description you are talking cossie here ?
In which case you will most likely find around 0.6/0.7mm works best.

As above 0.6mm m8.

 

some posts upper you sad:
"STOP right now, you will kill your engine on these plugs at that power.
Either as said or better still IK31 plugs 0.6mm gap.
PP8 only good for stage one or std, way way too hot for anything more."

where is the true?
This question is actual for me too...

 

Bugger I did not see that was half asleep.
PP8 are NOT suitable for stage three as they are way too hot and will likely melt, best to use either 071 or even better IK31.
AGPR12PP8 are MOTORCRAFT not DENSO.

Hi Tabetha when you buy a set of MOTORCRAFT AGPR12PP8 what you find inside the box is a DENSO spark.
I bought two sets, one from BUTONPOWER and the other from my local FORD dealer and here are some pis of what I found inside the box on both sets:







Which is the brand of the sparks you suggest?

Thanks
