Description
The Fuel-It! BMW E-Chassis and F-Chassis Port Injection Kits for N55 engines are the ultimate fueling solution for high-horsepower BMW builds. These systems add six supplemental low-pressure fuel injectors, enabling fueling support for 1000+ wheel horsepower when running E85, methanol, or other performance fuels.
Designed for serious power applications, these kits utilize precision CNC-machined manifold spacers or optional complete intake manifold replacements to deliver consistent fuel distribution, excellent injector placement, and long-term reliability.
