EFI Fuel Rail Adapter - GM/Mopar

The NITROUS EXPRESS EFI Fuel Rail Adapter (Part #16185) is a precision-engineered fuel system component designed to integrate nitrous oxide injection into modern GM and Mopar electronic fuel injection platforms. This adapter serves as the distribution hub that bridges aftermarket nitrous systems with factory EFI fuel rails, enabling seamless nitrous oxide delivery without requiring major fuel system modification.

Built with the dimensional precision required for tight OEM fuel rail compatibility, the adapter accommodates both General Motors and Mopar applications with standardized EFI rail profiles. The compact 2.7 x 2.4 x 5.85-inch form factor minimizes installation footprint while maintaining full flow capacity. Weighing only 0.15 lbs, it introduces minimal added mass to the fuel system assembly. This adapter is engineered to maintain factory fuel pressure regulation and integrity while allowing the nitrous kit to inject oxide charge at the optimal pressure point for maximum performance gains without destabilizing the base fuel delivery system.

This component is essential for street and track builds where nitrous oxide augmentation is planned from the outset. Performance builders working on GM LS-series, LT-series, or modern Mopar Hemi platforms rely on this adapter to maintain clean integration between OEM fuel infrastructure and aftermarket nitrous systems. The adapter eliminates the need for fuel rail replacement while preserving all factory sensor and regulator functions—critical for modern vehicles with integrated engine management systems that monitor fuel pressure, temperature, and delivery rates in real time.

NITROUS EXPRESS is recognized in the performance fuel system market for manufacturing application-specific adapters that meet OEM dimensional and pressure tolerance standards. This EFI fuel rail adapter is manufactured to exact specifications required for proper fitment on late-model GM and Mopar fuel rails, ensuring reliable connection and consistent performance across repeated nitrous deployment cycles.

Part #16185 is stocked and ready to ship from TacticalSurplusUSA. Verify fitment against your specific year, make, and model fuel rail before purchase.
