I am in the process of changing my spark plugs on my '02 Outback but had a question. I did not want to damage anything so I thought I would post. There is a rubber boot that is attached to the spark plug wire and creates a seal to keep dirt away from the plug itself. What is the best way to remove the boot so I can get at the plug. The rubber boot has a very tight fit between the plug and the engine. I do not want to damage the rubber boot but can anyone suggest the best way to get the boot off the plug. Is it a simple matter of yanking on the thing or is there more to it. Thanks
