BMW M3/M4 S58 WMI adapter

A WMI (Water-Methanol Injection) adapter is used in vehicles for water-methanol injection systems. Such systems inject a mixture of water and methanol into the intake tract of an engine to improve combustion efficiency and reduce the engine temperature. This can lead to increased engine performance and efficiency. The adapter plays an important role by enabling the safe and precise introduction of the water-methanol mixture into the engine. Such systems are often used in performance-oriented or tuned vehicles.
