No, I'm not going insane by posting this here. I'm posting on behalf of chadow427, he dosen't have easy internet access.

Anyways, he has the 2000 SSEi with all those go fast mods for the SII

He needs to know what would be a 2 and 3 stages cooler plug, what the gaping should be, and any brand that would be prefered.

thanks!

-John

I only got the one range cooler plug in the NGK tr55ix plugs, I think the next one cooler is the tr6ix or something like that. I'm not at that stage yet. I also have a .55 gap and that might be a bit big. I don't know if any of this helps or not.

After my recent mods (3.4 pulley and Intense PCM) I followed Rogue'* advice and went with the Autolite 605s, gapped .057. That'* a one range colder plug. So far, they're doing fine, but it'* only been about a month.

ok, we're missing one heat range....
104 = 1 or 2 heat ranges colder?
103 = 2 or 3 heat ranges colder?
