Standard Ignition US-678 ignition starter switch for the 2004-2010 BMW X3 and other vehicles sends power from the key to the ignition and starter circuits. It is engineered specifically for BMW vehicles.
A worn switch can show up as a key that sometimes fails to start the engine, or a starter that cranks only now and then. A weak battery, a tired starter or a corroded connector can be behind those signs too, so find the cause before you buy a switch.
The 2004-2010 BMW X3, the 2003-2008 BMW Z4 and the 2001-2006 BMW 325Ci fit this switch, along with many other BMW models. The 2003-2008 BMW Z4 takes one. If your BMW is not named here, look up its model and year in the "Vehicles it fits" section.
