KB owners! What Plugs when running 17lbs?

[black03]

Also what pulley should I get as a non slip pulley? I want to run 17lbs? Thanks

Car came with AGSF-22's, ive tried denso IT24's, car stumbled bad at low rpm so I went to agsf-12's and car ran great. I ended up fouling a couple somehow and replaced them with autolite AR103's. Car ran strong but had a low RPM stumble so I am not using AP103's and stumble is gone.

I'm running Denso IT-22's and haven't had an issue @ 16lbs. I was thinking of going back to NGK TR-6's or maybe the 55's when I cahnge em next.....

KB will likely void your warrant if you use an aluminum pulley, keep that in mind.

I'm using TR6s gapped at .040 with 15psi. The car runs perfect.
