The 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.
