I know that you're supposed to go with a colder plug when you use nitrous. I was wondering if you guys have any idea which brand and part # worked best for you. Thanks

NGK TR6s

Picking a copper conductor, colder plug is the main thing. NGK or Autolites are good brands to choose from.

Check out the sticky at the top of the nitrous forum.

Great idea..... that's where this should have been posted.

I ran TR6's gapped at 35 or 30...cant remember, anywho...it's the typical one that N20Outlet sells (or was it HarrisSpeedworks? I bought so much N20 crap from both companies I can't keep what from where straight...my apologies.) and they worked fantastic for me.

Also, I didn't run my nitrous that much, and when I pulled them after a years worth of daily driving duty, with a total of 6 nitrous hits on them, they were as tan as could be. I thought they might have been fouled, but they were in great shape after 14K miles.

NGK TR6 gapped @ .35 for street used/ 150 shot and below, TR7's or 8's on 200+ or for race use is what i go by, i gap the 7's or 8's at .30 Autolite 103's are good too. DO NOT USE PLATINUM TIP PLUGS!

We stock the NGK TR6s...they are under the stocking #4177 at your local parts houses also...Advanced Auto parts and O'Reiley's are 2 national companies that I know carry them

Thanks guys, you've been a big help. I'm gonna go with the NGK TR6's

Autolite AR103s work great and have a shortened ground strap.

Rather than making a new thread I thought I'd ask here being the original question was answered. I just installed LT headers and put in some tr-55 NGK plugs. I have a 75 wet shot kit I'll be hooking up soon. What am I risking if I run with these plugs? The manufacturer heat range is 5, while tr6 plugs are 6. I'm unfamilier with these numbers, but does that mean the plug is cold enough?

Ray@NitroDaves

the TR-5 and TR-55 are stock heat range plugs, the difference is what they are pre gapped at

the TR-6s are 1 step colder than stock

the Tr-55 would be fine for NA use but are the wrong heat range for nitrous
