spark plugs- tr55 or tr6 if i plan on nitrous down the road Im about to buy lts and a y, so while i had all that out of my car i figured i would change my plugs to make it easier. I havent changed them in the 11k ive had my car because im scared of trying.. ive heard its a PITA.
so my question is:
I anticipate buying about a 100 shot down the road.. maybe 6months, maybe a year, maybe not..
would it be a good idea to go ahead and put tr6's in, and at what gap, or shoudl i just run tr55s?

TR6'ss!!! They are great plugs and just a step or two colder than tr5's. They spark great. Just make sure if your are planning on spraying gap them between /038-.040*. Anything over could possibly need a few degrees timing taken out.

You Know I learned a VALUABLE leasson last week. Use ONLY good racing plugg's if you are going to play hard 
HAD I been running NGK's I would have a dead piston in number eight right now.
GOOD thing I was running Autolite AR94s! Number eight went lean and the copper plug slowly melted it self not hurting a thing saving the engine! Re-jettrd Number eight and stuffed AR93s back in her and upped the shot to a full 200 and let her ripp!
Four N2O Dyno Pull's and four full N2O pass's later all looks great !
I would bag the NGKs and get a set of Autolite AR94s

One of the reasons I changed was better street maners. I have ran NGKs for 15-20 years on the street. Never even though twice about it. Now that I can see the effect on the Dyno and on the street I have noticed my car run's cleaner with the AR plug's in it
BTW the plug got melted on a small 150 shot
