Use Champion C57 and if you still have the misfire close the gap to .5mm

its not about not needing them mate, they allow you to run a larger gap, hence better combustion.

But yes they are very dear

I'm just put C57C's in mine, apparently they don't last very long though

why wouldnt you use the champions , they are a good cheap plug that lasts around 1500-2000 in most cases and only cost around Ł20
