please for the love of god dont call it nos, it is nitrous unless its the N.O.S. (nitrous oxide systems) brand even then its pronounced N-O-S.
And not to be a dick but you have a mid-high 8 sec car and you dont know what plugs to use?

Maybe some of the nitrous gurus will chime in for you even though you called it naaws..jk

Sorry but over here everyone calls it nos, Ok nitrous. It runs 12:1 compression, Running on c16. It starts to miss and carry on then put new spark plugs in it and its fine.

Hi Tim - I have been speaking to Phonsey about this too - give him a call and he will sort you out or have a read of this - http://www.ls1tech.com/forums/showthread.php?t=846230 about half way down the page.

Your car looked awesome on the weekend by the way.:hail:
Watch out though - I'm only 20MPH behind you now.:lol:

I would go NGK TR6. Perfect plug for boost, or spray. Nice cold plug to keep from overheating and you can get em for less than 2 bucks a piece. Pretty much pre-gapped. :)

Yup, I had bought some tr8's and after talking to more people and thinking of it more I returned them for a few sets of tr6's. They work and are cheap, change em once a season and give her shit :D

I think for a 300 shot you're going to need something a little colder than a tr6...

I use NGK 11's for anything over 300 shot.
Doesnt mean I'm right but thats what I use.

You idiots that are telling someone thats running a 300 shot to run TR-6's need to shut the fuck up. Your bad information will cause someone to damage there engine.

10's or 11's would be fine. We've used 10's up to around 400 hp of nitrous.We have also used autolite ar3932's but they are harder to read.
