Unrestricted Dual Open-Air Design: Completely replaces the restrictive factory airbox system to create the largest, highest-flowing intake on the market. This dual open-air configuration maximizes the volume of cold air drawn into the S63TU4/N63T3 4.4L twin-turbo V8, ensuring optimal breathing efficiency.

Massive 6" Velocity Stack Air Filters: Upgrades the system with massive 6-inch reusable air filters featuring a velocity stack design. This engineered shape smooths the incoming air, eliminating turbulence and drastically increasing the velocity of the air charge entering the turbos for superior throttle response.

Smooth 3" Aluminum Piping: Features 3-inch smooth aluminum intake pipes that connect perfectly to the turbo inlets. Finished in a premium black powder coat, these pipes not only provide a stealthy, "greater than OEM" look but also effectively combat radiant engine bay heat.

Aggressive Jet-Fighter Induction Roar: By un-corking the 4.4L V8, all components work flawlessly together to produce an aggressive, race-inspired induction sound. It transforms the acoustic profile of your BMW, making it sound (and perform) like a fighter jet under heavy acceleration.

Dyno-Proven Power & Broad Fitment: Delivers proven peak power gains ranging from +12 to +20 HP without any extra tuning required (dependent on fuel and elevation). Designed as a direct fit for BMW F90 M5, F91/F92/F93 M8, G30 M550i, and G14/G15/G16 M850i. The kit conveniently includes two sets of silicone couplers to accommodate both Competition and standard models perfectly.
