I'll have you know I used plenty of elbow greese and Ive been eating plenty of weatabix, I was using a sparkplug tool, but you may aswell use your teeth with the amount of leverage you get with that thing I tried using a socket but didnt have a bit that would fit over the plug Im sure ive got one somewhere but was trying to see if there was a way to do it with out having to go n buy one to be used once, seems like I might have to. It doesnt help that they're down a sort of tunnel. Thanks for all the replies
