Description

The Burger Motorsports JB4 Water/Methanol Injection kit is designed for Gen 2 B48 and B58 BMW engines, allowing for significant power gains on pump gas. This system integrates with the JB4 tuning system for precise mapping and includes a 3.5-gallon stealth tank, an Aquatec pump, and a BMS BM10 nozzle.

The WMI kit provides cooling benefits similar to race gas or E85, enabling more power than either fuel alone. Its integration with the JB4 system ensures safe operation by monitoring flow and backing down performance if the tank runs empty. Boost is managed to prevent detonation upon initial acceleration.
