Spark plugs for nitrous use
I have a 383 ci at 11.5.1 compression. The nitrous dual shot I am using will be 100 hp each. What is better to use, Autolite's copper AR134 or AR132? What is your preferred plugs?
THANKS

The AR134 would be the hotter plug, approximately equal to the NGK R5673-8, the AR132 is more like the R5673-9. The R5673-8 or AR134 would be pretty good to use on a 200 shot.

Yeah, that usually looks pretty good. That's one step colder than what I usually run N/A.

Each engines different I guess. Yes I run a 7 on the motor, typically -8 for around a 200 shot but not much more and 9 up to around 400 and 10 over that.

I agree with John, I have used NGK-7 on motor and a NGK-8 on the spray that was about a 175 shot or so and has worked out fine. But every engine is different.John_Heard wrote:Each engines different I guess.
