Talk to JDM today and they said my HT0 plugs should be gaped to 30 and they come gaped to 45. I didnt think these plugs could be gaped since they have a complete "bridge" across instead of just a single free bar. Do I need to gap these? If so, how do I do it?

yes you should gap them.... I bought a tool from our local parts guy to do mine....

They need to be gapped.

What kind of tool do I use? Is 30 the right amount?

david01130

I guess I need this?

PolkThug

yep, there are a couple versions of that.

Yes, you want to close the gap from the factory specs. How must boost are you running? .030 is fine if you are running 10+psi. Our car makes around 9-9.5psi and is gapped at .036.

Ill be running a 3.4" pulley so like 9.5psi? I heard it needs to be gapped at like .032 or am I wrong.
