Performance Tool 3/8in. Drive, 5/8in. W80533 Extended Spark Plug Socket
The Extended Spark Plug Socket 3/8in. Drive, 5/8in., Model# W80533 by Performance Tool (Wilmar Corp) is great because of the quality you get for the price. At around $5, this socket is incredibly easy on the wallet. Plus this socket is also deeper than other comparable tools at 5 inches long. This extra length is good if your spark plugs are in a hard to reach place and you don't have an extension bar to use. The final reason I have decided to include this tool on the list is because it has a knurled design. This increases the grip of the socket, which is good to have if you ever get sweaty palms while working.
