    im in same boat. TR6 is the best way to go by NGK, stock ones will be fine for the shot that you will be throwing at it, and from what i heard from speed shop the plugs wont ruin the daily drive, tuning might?? a lil.

    but i think the TR6 comes with a .35 gap which is still perfect, but lots will say to gapped them to .38

    I hate to recomend alternates but Autolite 103 or 104 @ 0.038 will fire correctly under NO2, AC-Delco 41-913 @ 0.042 will provide a good streetable alternative.

    People tend to hate good plugs under NO2 but these have proven out.

    BTW: NGK makes the AC-Delco 41-913, they're pretty much a TR-6 equivalent as are the Autolite 103.

    Make darn sure your wires are OK. Only a read here but good info:

    Had that all wrong on the NGK #, sorry.

    Streetable and safe the AC-Delco 41-913, more streetable but not as safe the AC-Delco 41-919

    Autolites have been a favorite if you really plan to use your nitrous.

    TR6s at .038 for me. The colder plugs and nitrous tune cost me about 10rwhp N/A on the dyno, but when on the juice...look out!

    I always use the AutoLite AR 94's and if your going over 150 I would use AR 93's. I'm not a fan of the TR6's either. I prefer a racing plug that is designed for high cylinder pressures such as the AR series from AutoLite.
    When you see the plugs you'll see what I mean.
    Don't be afraid of the bottle!!! Be afraid of your tune!!!

    I don't have the details in front of me, but basically the timing and fuel are adjusted at 95% WOT when the nitrous is activated. My TNT wet kit made about 140rwhp on the 100shot jets with a good tune and a nitrous-friendly cam.
