This is a flow-matched set of professionally remanufactured genuine OEM Bosch IV marine fuel injectors, designed for a wide range of MerCruiser MPI engine applications. 
 
These injectors are built to match the original OEM specifications used in engines that commonly utilize part numbers 12609192 and Bosch 0280158165. They are a direct replacement, providing precise fuel delivery, smooth engine operation, and reliable performance in demanding marine environments.
 
CS Performance is a certified ASNU Service Center. All injectors are thoroughly cleaned, tested, and flow matched using ASNU professional equipment to ensure they meet or exceed OEM performance standards.

Why choose OEM remanufactured injectors?
Unlike many aftermarket injectors on the market, genuine Bosch injectors are built to a higher standard and engineered specifically for marine fuel systems. When properly remanufactured and flow tested, they provide more reliable performance, better consistency, and longer lifespan compared to low-cost alternatives.
 
Flow Matching
The ECU controls your injectors as a set. If injectors are not closely matched, some cylinders can run slightly rich while others run lean.
All of our injector sets are flow matched to within 3% or better, which meets or exceeds the typical factory standard of approximately 5%.
For customers looking for the highest level of precision, we also offer an optional 1% flow matching upgrade with documented test results.
 
Quality and Testing Process
Each injector goes through a comprehensive remanufacturing process, including:
Electrical testing (OHM test)
Full disassembly and inspection
Multiple ultrasonic cleaning cycles
Reverse flow backflushing
Leak testing under pressure
Spray pattern analysis
Flow rate testing and matching
Reassembly with new internal components (filters, O-rings, seals)
Final quality control inspection
 
Lifetime Warranty
All of our injectors are backed by a lifetime warranty. If the injectors ever become clogged or fail under normal use, we will clean, test, and service them to restore like-new performance.
