It turns clockwise, has a 6-groove pulley and uses plug code 335. Easy Life Markets sells it as a single alternator for owners who have matched the number 12317510599, 12317510597 or 12317510593 to their car.\u003c\/p\u003e\n\n\u003cp\u003eBMW sixes of this period are known for running a long time, which means many are now on their second or third alternator.
