This is a flow-matched set of 8 professionally remanufactured genuine OEM Bosch UPGRADE fuel injectors, designed as a direct upgrade replacement for the original Rochester 17109596 injectors.
 
These injectors are a different OEM part number than the originals, but they match the required fitment, flow rate, and electrical impedance, allowing for a seamless installation with no modifications required.
 
These Bosch upgraded OEM injectors feature improved internal materials and nozzle designs compared to older stock units, offering enhanced durability, consistency, and long-term reliability.
CS Performance is a certified ASNU service center located in northern Minnesota. All injectors are thoroughly cleaned, tested, and flow matched using top-of-the-line ASNU professional equipment to ensure they meet or exceed OEM performance standards.
