Genuine replacement HFM for F10 535d, F02 740d, F15 X5 35d. The airflow sensor or HFM (Hot Film Meter) is hugely important in the performance and fuel economy of the engine. Faulty airflow sensors usually cause rough running, poor idle, lack of performance, misfires, and higher fuel consumption. There may also be fault codes and check engine lights for air:fuel mixture, lean conditions, rich conditions, and others.

This is a Genuine BMW HFM 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.
