Spark plug socket 1/2" drive, 18 mm with retaining spring

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