Negative Positive
Title: Definitely worth it.
Review: I would rather buy this $40 tool and an hour of my time to replace my spark plugs than pay someone $150 to do it for me. The next time, all it will take is the spark plugs and another hour. It it plug and play, so it really couldn't be easier to use and it works like a charm. All you need is a socket wrench, one socket for the tool, one socket for the bolts on the mounts, and a wrench for nuts on the mounts. Super Simple.
