Best sparkplug for turbocharged honda?

[89coupe]

My friend has a 2000 Civic SiR with a single turbo application. What plug would best suite his car?

A part number would be great? Also, what gap should they be set at?

Thanks,

B

were ever it does not miss.... should be about half the factory spec...

So factory are 0.052 so .026 is what you're saying? That seems really low. I gap the plugs on my car at .032 I would have guessed around the same.

start at .030 and increase till you get a miss
