crank angle sensor and speed sensor??

Can anyone tell me where to find these parts, or what other names they might go by? I was told that when replaced in conjunction with one another they would solve a spark problem in my 735i, but I have not been able to find either one. I have found an ABS speed sensor on one site but I dont think this car has ABS.

Crankshaft sensor or ignition sensor and speedometer sensor. I get most of my BMW parts from two websites: www.egermanparts.com (http://www.egermanparts.com) and www.bavaparts.com (http://www.bavaparts.com). They seem to have them all and are less expensive than everyone else.
