What Spark Plugs!!!

[tonymo05]

I Have A 99 Camaro Ss' Im Doing The Headers And Thinking Of Adding A 100-125 Shot Of Wet Nitrous..im Going To Go Ahead And Replace The Plugs...

What Are The Best Plugs To Get Without Messing W/the Gap. And So That The Car Will Run Right When I Dont Use The Nitrous.

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:

i use autolite 104. i burned up a set of TR6 at the 200 level.

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.

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.
