Re: plug wire removal
Yes the spark plug boots just pull off. Replacement boots should be for 7MM wires and are available from automotive parts suppliers. The ones for 8MM or 9MM wires are too big. Take a little liquid dish washing soap to lube the existing wire and they'll slide on/off much easier. If you decide to replace the metal connector on the end of the wire, stainless steel works the best. I've used the standard metal ones and they turned to rust in a matter of weeks.
