Spark Plug Question
I have a 1994 Z28 camaro that I was debating if I was going to spray between a 75-100 hp shot. I just got new plugs installed (TR5's NOT TR55's) and was wondering if these spark plugs would work? I guess they are the same heat range as the TR55's but the gap is only .035. I don't want to have to change the plugs again if I dont have to. And also out of curiosity, I was wondering what the difference would be with the smaller gap...whats the difference between have different gaps? thanks-bryan

You will want to go to a colder heat range plug like the TR6. This is done to reduce the chances of detonation
The wider you gap the plug the more spark you have to ignite the A/F mixture but the easier it is to blow out the spark. You want the plug gapped to where you have enough spark to ignite the mixture but not blow out the spark.
That is why Nitrous applications gap the plugs a little tighter than NA
