RVNG S58 Port Injection Kit (G8X)

The RVNG S58 Port Injection Kit provides reliable supplemental fueling for high-power S58 builds while retaining the factory intake manifold. The system is designed to integrate cleanly with OEM components and maintain proper fitment without the need for a custom manifold.

This kit delivers true multi-port injection and is compatible with all fuel types including full E85. It is available with or without injectors. Injector-equipped kits include genuine Bosch Motorsport injectors that are modified and flow matched both statically and dynamically. Flow data is included to support accurate and consistent tuning.

The RVNG fuel rail features a true full-bore AN6 internal design to prevent pressure drop under high load. Integrated injector retention locks mechanically secure each injector to the rail, reducing stress on the factory plastic intake manifold and allowing the rail to be removed without fuel spill during service.

All fuel lines are smooth-bore PTFE paired with motorsport-grade billet fittings. No rubber hose or plastic fittings are used. The kit includes all required hardware and is compatible with popular injector controllers such as ReFlex, AIC, and JB4-based systems.
