Product Information

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.

Features:
- More Power: + 6 HP @ 7000 RPM, + 5 LB-FT @ 7000 RPM (coupled w/ engine software).
- Internal diameter increased for increased flow.
- Made of aluminum and powder coated black for maximum durability.
- Simple and quick installation.
- 50 State Emissions Legal: CARB EO D-176-18.

Mass Air Flow Sensor

Mass air flow sensors are tasked with measuring the amount of air entering the engine via the intake. This mass air flow sensor is known as a hot film sensor which will suffer performance deterioration over time. The sensor is designed to be self cleaning. A faulty or non functioning mass air flow sensor will cause a check engine light and in some cases cause a limp mode. The best way to diagnose a faulty mass air flow sensor is to disconnect it and see if engine idle or performance improves.

Mass Air Flow Sensor Failure Symptoms
  • Check engine light illumniated with OBD codes related to MAF sensor faults
  • Engine has rough idle and/or stalls
  • Short term fuel trim is rich at idle or lean under load
  • Constantly runs rich or lean
