plug gap...what is it again?

fst100 · 04-28-2008

L67 with a vs cam and supporting mods. im trying to tune for 89octane and thus far im having some luck(just a bit of knock up top in PE mode). im running AL103 and i believe they are gapped at 0.044. im using an m2 nozzle and was wondering if the gap range i have is correct or should i increase the gap to 0.050? stock gapping with the copper plugs IIRC is 0.055-0.060 on non-alkied cars.

You tighten the gap note increase it with the alcohol injection. Your gap now is were you need to be. I ran close to the same gap on Autolite 103's
