I've been running a tr6 plug with my 100shot, I am going to a 200 and Im figuring I should go with a tr7. The bad thing is I dont know a whole lot about spark plugs. There is different types of Tr7 plugs and not for sure which would best suite me. Any info given would be a bunch of help, also if anyone has a write up or something explainning certain spark plugs, that would help me out too. I tried looking in the stickys but couldnt find what I wanted.

there is no such thing as a tr7, you want a heat range "7" plug.

the plug you want to run is a non projected #7 plug which is ngk BR7EF, ngk stock #3346.

^yeah, thats what I thought.. It just seems like so many people refer it as a tr7 so I went with it. thanks for the help, thats the plug that looked like the best from reading up on them.

For a 200 I would probably step up to a BR8EF. 7's would probably work, but I like security

imo BR7EF would be best

You better start learning or you'll end up a statistic. Read the nitrous stickies, along with reading in general and hands on experimenting. BUT, there's only a handful of guys here that really knows their ****, so beware.

If you're stepping up to a 200 hit, I hope you AT LEAST have a racetronix hotwire kit installed and hope your fuel system can handle it. Make sure you pull timing and I would go with an 8 plug (B8efs, part #1049). You can drive around with 8s if your tune is right.

like what i was asking in the other thread wouldn't that be four steps colder than stock. dont u think thats a bit overkill?

I dont understand how you are getting that? please explain. we are going by ngk's heat ranges.

i have everything ready on my car, everything has been upgraded. I have always planned on doing a 200, I just started it off with a 100 to get a feel for it.

because ((8-5 = 3) + (going from projected to non = 1) = 4)

i always understood going from a projected to a non is worth a full heat range point. can anyone prove this wrong? does ngk use one heat scale. From what know the TR has it's heat range, the BR has it's heat range. when you go TR to BR its -1 right there.
