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 O2 sensor 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.
