Best Spark Plugs for Supercharged engine

Seb_F

Anyone got any suggestions for the best sparks to use on a stage 2+ supercharged Z22?

Mine stutters a bit when cold (as if it weren't firing on all cylinders) and I've put it down to sparks, though I may be wrong?

Any suggestions on problems/solutions/spark plugs welcome 🙂

Thanks

What plugs do you have in at the minute?

I use ITV16 in a 240bhp and ITV20 in over 300bhp

I have the standard plugs in I think and they aren't liking something. At least I don't think they are and it is actually the plugs.... unless it's something else causing it to stutter and misfire on mild load when cold....?

As you can see from my thread in the above link, i've reverted back to standard plugs. GM seem to be the best.

Strange, there must be something going on in mine at the moment for it to be unhappy then!
