Restore and Enhance Your Marine Engine's Performance
Upgrade your Mercruiser or Indmar engine with our precision-engineered fuel injector set. These injectors are a modern performance upgrade for the original 885176 and 12567905 units, which are known to suffer from clogging and inconsistent flow over time.
Advanced Technology & Testing
Our upgrade injectors are dynamically flow-matched to guarantee consistent fuel delivery across all cylinders. This meticulous matching process, combined with the injectors' rapid response and linearity, leads to superior idle characteristics and significantly improved throttle response.
Every injector undergoes rigorous flow testing at 43.5psi using CF-16B calibration fluid. This ensures high-accuracy fuel maps, allowing you to optimize your engine’s fueling for better MPG and peak horsepower.
