A 14mm Bi-Hex (12pt) 3/8" drive spark plug socket with longer than standard length barrel, narrow walls and wobble joint head designed to fit the narrow spark plug recesses commonly found in modern vehicles. The wobble function is particularly useful for accessing BMW spark plugs which are installed at an angle of > 5°, where a standard spark plug wrench does not fit. This professional quality tool is manufactured from chrome vanadium and has an internal spring clip for reliable spark plug removal and installation.
