This part is listed by BMW as BMW part number 12517513554 (12 51 7 513 554) and is described as a Main Engine Wiring Harness. This is the large wiring harness for the M54 engine in 2001-2/2003 E46 325i and 330i. Perfect for replacing a damaged coil harness. It does not include the harness for the ignition coils (separate BMW part #12517551908).

This harness is also required when converting from later MS45 to earlier MS43 engine management, such as for Spec E46 racing.

This is a Genuine BMW engine harness with a two year warranty. Buying a Genuine part will usually be more expensive than an OEM or aftermarket brand but you are assured that it meets BMW's designs for fitment, performance, and longevity. It will also be the very latest design, incorporating any updates or revisions that an aftermarket brand typically will ignore.
