Spark plug socket 18 mm with retaining spring, 6-point

Two solid stainless steel springs grip the 6-point of the spark plug and press it against the stop of the brass guide bushing. Now the spark plug sits exactly perpendicular to the axis of the socket. The installation can be done without damaging the threads in the engine block and without pressure on the insulator of the spark plug.
