True but tr6 will work perfect, gap them at 0.35" and spray away. Many people have used these with perfection and for that small shot you will be fine as long as everything else is good with your car?

worked wonders? lol a tr6 is NOT a nitrous plug, its that simple. You'd be a lot better off running the CORRECT plug which is a br6ef. Extended tip spark plugs are for emissions, not making horsepower... FACT.

True again, if your looking for a nitrous only plug that the br6ef is it. If your looking for a plug that will work with nitrous then the tr6 is the plug. The difference is the br6ef is made for nitrous and if thats what your asking then thats what you need.

if its a little dinky dry shot you probably wont ever have any issues out of a tr6. br6ef is better for the bottle, though.

non extended tip plugs work perfectly fine without nitrous, you're not giving up one thing. I run r5671a-8 plugs on my car..... made the same power as a bkr7e projected tip, while also being non-projected and heat range colder... this was NA.

I know that as well, but if he wants a nitrous only plug then he should get the br6. But if he wants a plug for street and nitrous he can use the tr6. both I have tested before on the street and dyno and didnt lose any power at all. But when N/A gapped at .035 it was sluggish then I put the gap back to .50 it made more power. So he has to figure out if hes gonna run nitrous all the time and sacrifice a bit of power while driving N/A.

Sorry but I dont really agree here. Seen too many times people switching from TR55's or TR6's to BR7EF and lose no power at all...

OP, I would run BR6EF with that small of a shot. BR7EF if you think you'll ever step it up to the 125+ range.

im still up in the air with the plugs maybe this will help you guys narrow it down for me.I drive the car daily to work and back i only put about 20 miles on it a day i take it out saturdays to cruise and some times i will run it, i probably only run it 1 or 2 times a month now with the spray i will probably use it every time i run so what would be the best plug. Im thinking the TR6 ..am i right but what should i gap it at

dont run a projected tip plug with n2o..run the br6 you will be fine..for some reason on this board people say to run a projected tip plug for n2o but if you went to a hard core racing board with heavy n2o users the first thing they would tell you is ditch the projected tip plugs..**** even in the n2o section and drag racing section on here they will..
