Show original supplier description
The AC Delco 12613412 fuel injectors are a set of eight genuine GM components, designed to be a direct replacement or an upgrade for various LS-based engines. These injectors feature an EV6 plug style and a flow rate of 50lb/hr at 58psi, making them a popular choice for enthusiasts looking to enhance their vehicle's performance, particularly in cammed trucks. With an OEM truck height of 47.4mm and USCAR connector type, these injectors are listed as compatible with L96 engines, as indicated in their application sections. They are also flex-fuel compatible. The product is identified by GM Part Number 12613412 and is also known under ACDelco GM interchange part numbers 217-3412 and 12613412. As electro-magnetic valves, these fuel injectors meter fuel into the engine's intake manifold or cylinders for combustion. The engine management computer controls them by applying electric current to the solenoid winding, which opens the needle valve, atomizing the pressurized fuel into the intake airstream. These original equipment injectors are manufactured to provide the same performance, durability, and service life expected from GM vehicles. Conversion harnesses are available for Multec to EV6 applications.
