Well finally got my car going off to the dyno on the weekend and am looking at buying a few sets of plugs for the tune.
What heat range plugs would be my best option?
S13/4/5 run heat range "6"
GTiR run head range "7"
… and I was looking at running an "8" heat range in my GTiR SR20 (would even run a “9” if I could, pull as much heat out of the cylinder as possible).
Has anyone ever used a colder plug like this on a GTiR motor?..... Reason being I had "8's" in my S14 SR20 and it would foul up, where as "7's" would run very clean.
FWIW, I’m running a stronger Mitsu waste spark ign setup & module (no GTiR dissy & single ign coil) and am looking at running cheap common v-grove copper plugs and changing them often.
Thanks in advance.
