this is a rather huge deal, I have an 01 H6 and have the local mechanic do it because there is so much involved. you first need to remove the with the H6 logo on it. the one that sits on the top of the car and is for looks only. you then will have to remove heat shields and other hoses and wires that get in the way. with the H6 does no have spark plug wires or anything of that nature, the coils sit on top of the spark plugs. each plug has a coil and each coil has a wire and plug that clips to a harness. these will all need to be unclipped and the plugs removed. gap and install new plugs, and then go in reverse order with putting the coil packs on and so forth. if you can find a good mechanic it would better to let him do it as like I say this is project not for beginers. good luck
