Everyone knows spark plug changes are suggested every 20k miles or so for tuned vehicles. Everyone also knows 2006+ BMWs requires a special thin walled socket to remove/reinstall the spark plugs. But what you might not know is the BMS socket fits like a glove and is only one third the price of a BMW socket! It also includes an integrated rare earth magnet to secure the plugs while raising and lowering them in the long bores. The BMS socket will never wear out like spark plug sockets with rubber or metal tensioners to hold the spark plug in. The RIGHT tool for the job makes BMW spark plug replacement a snap!
