The Dinan High Flow Air Mass Meters are a fantastic addition to the cold air intake on your E39 M5, giving your engine the boost it needs to breathe easier. These high-flow units come with a larger internal diameter, allowing air to flow more freely from the cold air intake to the intake plenum, which translates to increased power. Crafted from aluminum instead of the stock plastic, the Dinan Air Mass Meters are built to last and seamlessly integrate with your vehicle's existing electronics.
To make the most of this upgrade, pairing it with Stage 3 engine software ensures optimal engine management, resulting in impressive power gains while maintaining that signature BMW driving experience.
While the updated E39 M5 Air Mass Meters function just like their predecessors, they do have a fresh look. Unlike the original release, which had no branding for a stealthy OEM appearance, these new units proudly display the outlined Dinan logo, reminiscent of the popular E39 540i AMM. This change is sure to satisfy enthusiasts while allowing purists to easily spot the differences between the original and the newer models.
