Also a tip, you could call it, is that I know when I change my plugs it isnt the easiest to get them completely unscrewed with the wrench. What I did was go down to the Home Depot with a glow plug and found a nice rubber hose that fits snuggly over the gp. When I get the plug cracked with the wrench, I put the hose around it, its about 8" or so and turn the hose. Makes the one behind the IP very easy to get out.
