We actually bought the spark plug socket from bms! However the gap tool does look a lot nicer than my method..

Question on running 2 Steps Colder- thats an N20 plug right? Would you gap it to the same ~.20 for an N54? I daily on stock boost and wanted a thorough burn which is why I wanted to do stock bosch or one step colder. Isnt 2 steps good for very high hp, less so daily driving? I get that you would want protection against knock when getting on it, but I thought it comes at a price of fouling, decreased longevity, general poorer daily performance etc. I'm also in the Northeast with highly varying temps. I appreciate your thoughts.

I run these plugs on my one of my bone stock 335s

Itís the plugs used on the m3/4

.020 should do it

Longevity wise- probably wonít last as long as stock, but imo 1 step vs 2 step- negligible
