im trying to work out how to get them out of the block, i pulled the plastic cap off and found that each plug has its own coil pack, isnt that cool, but how do i get them off without breaking sumthing. There are charts which u can prolly get from supercheap or sum mechanical place which shows damaged sparkplugs compared to a good one, and gapping them u should get a feeler gauge ($10) and just tap them gently till the gap is at .8 which is what ppl seem to like. the feeler gauge is to measure the gap, do not use a hammer or pliers, and iridium plugs shouldnt be regapped too apparently
