I have been running NGK TR6's for about 5 years and spraying a 125 shot with no problems and just recently I sprayed a 150 shot. I am changing them to either the BR7EF's or B8EFS, I have not made my mind up yet. I am wanting to stay with the 150 and sometimes maybe a 175 shot so my question is will my car make more power by just going to a colder plug on the spray and with all mods in my sig what plug do you suggest. Keep in mind I do drive my car every day.

I run my BR7EF's up to a 175 shot. When I go 200 I'll change to an 8 range.

Br7ef is what need to be in there. No question on that one. It fits the combo to a T.

Thanks for the feed back guys. Should the car run better on the 150 shot by just changing the plugs?

They will keep it running.

They will open the tuning window up and keep everything safe. It will not really pick up ET.

When I first got my car I sprayed a 100 shot a few times on tr6, and went 10.02-10.04 all day. I did get slight detonation so I put in the 7's (the correct plug) and my only change and went 9.89. With 6 degrees of timing pulled (my 150 tune).
The One and Only time I sprayed the 150 on the 6 it went 9.88. With my only change being spark plugs. Put the 7 in it went 9.75 and would have went faster my next pass if I hadn't blown my hood off ending my day.

So I would not be surprised to see you pick up some more and run faster.
