Are the NGK TR55'* one heat range colder plugs? I'm going to start getting ready for the 3.4".

Gap them at .055", not .060"

Does gapping them at .55 help create a better spark?

*bump* I'd really like to know what a 0.55 gap helps with.

Only thing I can think of is that the spark doesnt have to jump as far and is stronger.

Would this apply with autolites too? or does the manufacturer really matter on something like this.

Would it be better to gap all plugs at .055? I gapped mine at .060 when i last did my plugs. Next time i do my plugs i will do the NGK'* with a .055 gap.

If you are looking for a comparison, I just installed a 3.4 with Autolite 104'* (2 ranges colder) gapped at .050.

I haven't experienced any KR or ignition problems.
