  Spark Plug Socket
by John on September 19, 2008

This is a first class tool for users of 4 stroke bikes with 5/8 spark plugs, top quality from Motion Pro! Used with the mini tool kit you just pop the whole case in your pocket along with a sparkplug and ride easy!



  Awesome

this is really great, especially the extension. I bought this just for the extension and gave the plug to a friend. You should considering selling the extension separately.
