BMW M5 High Flow Air Mass Meter Kit by Dinan for the E39 (2000–2003), black. Built to increase intake flow and complement your cold air intake while retaining factory-like manners.

Featuring a larger internal diameter, this kit lets air move more freely from the intake to the plenum, helping the S62 breathe. When paired with Dinan Stage 3 engine software, gains of up to +6 hp and +5 lb-ft at 7000 rpm are achievable with BMW-like drivability. Precision aluminum construction with a durable black powder coat accepts the stock electronics, and the re-released units carry the outlined Dinan logo for easy identification. It is 50-state emissions legal under CARB EO D-176-18 and installs quickly.
