I know that I have to run a plug different than I am using right now (Bosch +4). I will probably get either the NGK or Autolite and they are supposed to be gapped at .035 with nitrous. But my question is, can I use this plug at this gap all of the time and still be OK? I want to be safe, but I also want my car to run right on the street. Any help would be great. Thanks

 

yes you can. colder plugs does not really affect NA performance.

 

NGK V power, 0.035" Gap , 2 heat ranges colder

PN: TR-6 SN: 4177

available at your local advance auto, just give them the stock number and the plugs should arive a few buisness days.

 

I run the NGK TR6 gapped at .040.....no problems at all NA.

 

They are really more like a 1/2 heat range colder than the TR55 that are used for NA only.

 

I ran my best NA and NX time so far with Autolite 103's @ .040. So it runs great on and off the bottle. Times in sig.
