Spark Plugs

Do you guys have a clue on what spark plugs to use with my setup?

I have an S50B32, supercharged, 8.5:1 copression ratio, about 0.6bar boost...

the previous owner was using the ngk dcr8eix, and left me a new pack of them,

should i gap them? or will the original gap do?

thanks
Tom

you probably want one range colder than the stock plugs

Single prong plugs should always be gapped to be sure the gap is correct. Never assume.

I go with plugs from a hyabusa motorcycle. I would recomend NGK bp7es for regular gas and for Ethanol NGK BP8EVX
