Description

The MAD High Flow Air Intake (MAD-077B) is engineered to unlock the untapped potential of your BMW's B58B30 3.0L engine, specifically for the 2017-2023 BMW 540i G30 and 2019-2025 BMW 850i/850i xDrive models. It features a meticulously engineered, smoother, and less restricted airflow path to optimize performance gains. A custom-fit heat shield is included to actively deflect hot air away from the intake, ensuring only cool, dense air enters the engine for maximum efficiency. Owners can expect an enhanced throttle response and a more satisfying intake growl, contributing to a more engaging driving experience. This intake is compatible with BMW 5 Series (G30 540) and BMW 8 Series (G14, G15, G16) vehicles equipped with the B58B30 engine. Included in the kit are a High Flow Air Filter, an Aluminum Intake Pipe, a Heat Shield, and all required Mounting Hardware.
