When I look at the spring cleaning guide and recipes on gnttype.org, it says "For cars running 12's and down run AC R42 plugs..."
Since we are over a mile above sea level and thus the typical 12 sec run is a high 12 to low 13 up here, would I still use the R42 or the R43? I don't know if the plug recomendation is based on ET or boost that you are running. Any help? Know what I mean? Thanks,
Justin
