GFBV D763-1500D Dinan High Flow Air Mass Meter Kit - 2000-2003 BMW M5 - Fits 2000-2003 BMW M5

Aluminum - E39The Dinan High Flow Air Mass Meters compliment the cold air intake on the E39 M5 by further increasing the engine's ability to breathe. The high flow units feature a larger internal diameter enabling air to flow more freely from the cold air intake to the intake plenum for increased power. The Dinan Air Mass Meters are manufactured from aluminum, as compared to the plastic stock units, and have been designed to accommodate the stock electronics for increased durability and seamless integration. Stage 3 engine software provides the proper engine management to take advantage of the modification resulting in maximum power gains and BMW-like drivability.; While functionally the renewed E39 M5 AMM's are identical to their successors, the re-released units are cosmetically different. The original release bore no branding for a stealth/OEM look whereas these feature the outlined Dinan logo that was popularized from the E39 540i AMM. This oft-requested adjustment should please most while also allowing the purists to be able to tell the difference between an original unit and the later release.Features and Benefits: 50 State Emissions Legal: CARB EO D-176-18.; Internal diameter increased for increased flow.; Made of aluminum and powder coated black for maximum durability.; More Power: + 6 HP @ 7000 RPM, + 5 LB-FT @ 7000 RPM (coupled w/ engine software).; Simple and quick installation.Stage 3 Engine Software and Dinan Cold Air Intake recommended for optimum performance and drivability.DIN FIAFM
