I have question about the grp plugs.. Has anyone tried the PLUS or even know what thats supposed to do?? It seems like theyre making it like splitfire plugs compared to NGK racing plugs.. lol..
To be more specific, on NeoBuggy Adam states that he runs his engines box stock and does not add any shims for 30%. GRP's come shimmed from the factory with (1) .3mm aluminum and (1) .1mm copper for a total of .4mm already installed. So Adam certainly has shims installed in his engines, he just doesn't add any additional shims for 30%.
Good Luck.
