Nissan Skyline R33 Fuel Injector 370cc RB25DET (Non NEO)

The Nissan Skyline R33 Fuel Injector 370cc RB25DET (Non NEO) is an essential component of the RB25DET’s multi-point fuel injection system, delivering precision-engineered performance and factory reliability. Designed as a side-feed injector, it atomizes fuel under ECU control, providing each cylinder with a perfectly measured and timed spray. This ensures an optimal air-fuel mixture for efficient combustion, smooth throttle response, and strong, consistent power delivery while maintaining emissions compliance and fuel economy.

Constructed from a blend of durable metals, heat-resistant plastics, and fuel-safe elastomers, this genuine Nissan injector is built to withstand high pressures, temperature fluctuations, and corrosive fuel environments. Flow-rated at 370cc/min at 43.5 PSI, it’s ideal for stock or mildly modified RB25DET setups where OEM precision and dependability are paramount. Its tight flow tolerances prevent cylinder imbalance and eliminate the risk of lean or rich conditions that could lead to detonation or poor performance.

Unlike many aftermarket injectors that can introduce inconsistencies or tuning challenges, the factory-spec JECS-built unit integrates seamlessly with the ECU for stable operation and predictable fueling behavior. For enthusiasts maintaining or restoring an authentic R33 Skyline, this injector provides the perfect combination of efficiency, durability, and plug-and-play reliability—ensuring your RB25DET continues to perform with the smooth power and precision it was engineered to deliver. Not compatible with RB25 NEO engines.
