I think at stg3 your normaly ok to run pp8's...any more boost tho and they would be a bit hot imo. Best to ask who ever did your stg3 conversion tbh.

agreed but at £2 per plug you can afford to change them until you get a good set, I have seen one dodgy plug out of the 20 or so that I have bough and that was totally faulty. I would guess the missfire plugs need re gapping.

I have some Denso ones in mine from Reyland and haven't had any missfiring probs, and apparantly they should last longer too. The downside is that they were £11.50 each!

hot running plug, and was the probable cause of my meltdown,i used them after being incorrectly advised on plug choice.


071c is a good safe plug, but i have found they dont idle aswell as others....

im opting for iridiums this time i reckon

I think mines in need of another set as the car started spluttering like fook when i dropped it off at the bodyshop on Thursday, it's done under 200 miles since my setup at MSD and the plugs all together have been in since the rebuild 1500 miles ago.
The car currently has a set of ford O71 in it are these good enough for 21psi??

IK31 0.6mm gap, will be fine on stage 3 or 1, and idle better than 071's.

Cheer's for all the imput guys, im gonna try a set of 071's i think, i was told to gap them at 0.8 so will cut them down to 0.6, maybe why i've been getting a missfire at full boost.
