Facom 3/8" Drive Spark Plug
Socket - for 14mm (12pt) spark plugs (eg, 2007-on BMW 335 & 535 models with turbo 3.0L engine). Knurled end for fast
pre-tightening. Rubber grips to hold plugs in place. Standard
length - 10" (250mm). (Note- current production sockets have a flat/matte finish...better fingertip grip than polished chrome.)
