I'm currently running the plain tr-6 I was thinking of putting in the tr-6-ir (irredium,sp-ck.) Are these plugs o.k. with nitrous? I'm using a TNT 150 wet kit, just curious if they're worth the extra money?

 

Yes, they're the NGKs that you want for FI. I have the TR55 IXs, but run N/A. The TR6's are cooler. Any iridium plugs with thin-wire posts should produce much better flame propagation than standard plugs, even platinum, but who's ever dyno'ed their car before and after plugs, so who knows for sure???

 

they are ok for nitrous, I just wouldnt spend that much $$ on some plugs. The coppers work great.

 

so what plug would be ideal for a 100 dry shot on an ls1

 

NGK TR6's gapped around .035-.038
