Product Description

The GAMIjector and TurboGAMIjector fuel injectors are meticulously engineered to deliver precisely measured fuel to each cylinder in your Lycoming engine. They compensate for the inherent fuel/air imbalance in your engine(s), essential for efficient lean-of-peak operation and enhanced engine performance.



Save up to 40% on fuel by operating your engine(s) lean-of-peak during most flight phases. The GAMIjector and TurboGAMIjector injectors ensure an even air-to-fuel mixture across all cylinders in your Lycoming engine, enabling lean-of-peak operation. This not only saves money by reducing fuel consumption but also results in cleaner burning and less stress on the engine, contributing to more efficient, reliable, and safer operation.



  • Precision Calibration: Each injector is calibrated for unparalleled precision, promoting uniform fuel/air ratios.
  • Enhanced Engine Performance: By adjusting each cylinder’s fuel/air ratio, the injectors facilitate smoother, more efficient lean-of-peak operation.
  • Legal and Certified: Fully compliant, FAA and EASA STC’d, and PMA’d for nearly all models in the Lycoming fuel-injected engine fleets.
  • Data-Driven Design: Specifications are derived from GAMI’s advanced 96-channel data acquisition system, ensuring engine model-specific optimisation.


GAMIjector® Fuel Injector Kits

Each kit for Lycoming engines includes GAMIjector and TurboGAMIjector fuel injectors, O-rings, washers, gaskets (if applicable), STC and permission letter, Sample 337, Certificate of Conformity, Installation Instructions, Flight Manual Supplement, Identification Plates, and Fuel Line Tags.

Please note, fuel lines and upper deck seals or tubes (if applicable) are not included, and these items are not offered.


Installation Process

Installation is seamless and efficient, typically completed within an hour (slightly longer for turbocharged engines). The process involves removing old injectors, installing new GAMIjector fuel injectors without modifications, and completing necessary documentation to comply with warranty and regulatory requirements. Installation by a qualified mechanic ensures safety and compliance.
