spark plug prices....
why is there such a price difference in say a cossie plug to a skyine plug?? what are there difference in heat ratings of each and can any type of cossie plug be used in a skyline?? reluctant to spend silly amounts on plugs advertised for skylines when it could just be due to "skyline tax"
Asking here as most skyline owners havnt a clue and just pay someone whatever it costs to sort..
