Have any of you used the OTC 6918 Spark Plug removal tool? This tool is used to remove the spark plugs and its supposed to keep them from breaking upon removal. Its different from the Lisle 65600 tool as this tool is only used if a spark plug is already broken. Any feedback or reviews on the OTC 6918 will be greatly appreciated. I'm getting supply and parts together as I'm planning on a cam swap and running new exhaust sometime early 2014 and figured I'd go ahead with new spark plugs as well before tuning.
