systems. I had the HKS #7 Iridiums in there since Coz (no offence bro) recommended them, but they didnt work well at all in my Z and they were the same size as the NA plugs (reference pic)
and i had also been told that NGK didnt make a #7 plug for TT's - i had been sold the #7 NA plugs and those fouled during a dyno and had it running ruff anyway. So now i have a fresh set of #6 NGK TT plugs- but whats the story on these #7 Copper NGKs? Are they the TT length and is copper #7 the best plug for me running a new engine w/ td05's, 100shot, etc etc. Any help would be appreciated so i can order these if thats what i need. Thanks, Wagz
