Original BMW Microfilter Clean Air Channel for BMW 740i (1999–2001), 740iL, and 750iL (1995–2001)

Filtered air reaching the cabin of an E38 BMW 740i, 740iL, or 750iL passes through this Original BMW microfilter clean air channel, which carries air from the cabin filter housing into the passenger compartment. A cabin microfilter traps dust and pollen before outside air reaches the occupants, and the clean air channel is the section on the filtered side of that filter. This piece is a replacement for the ducting BMW installed at the factory, made in Germany and produced by BMW from April 1994 onward. It is sold as a single piece. Fitment data also identifies it as the instrument panel air duct for these sedans, which places it within the dashboard ventilation path.

Original BMW Parts carry a 24-month parts warranty.

One part number covers both V8 and V12 E38 sedans. BMW's parts data shows it on the 740i and 740iL with either the 4.0-liter M60 or the 4.4-liter M62, and on the 750iL with both the M73 and M73N V12. That makes engine changes during the E38 run a non-issue when picking this duct, and an owner of a long-wheelbase car uses the same channel as the standard-wheelbase 740i.
