Description
These Aren't Your Daddy’s Carb Kits. Back in the day, a hot rodder might slap on a bigger carb, turn a few screws to tune it, add a velocity stack and see if the car went faster. Or started. But we live in a more modern time. A time where fuel injection rules. And nobody rules fuel injection like Fuel Injection Clinic with their 4x775cc injector kit. These High-Z injectors utilize the latest technology to give great linearity and short-pulse-width repeatability. The injectors are specifically designed to be plug-and-play with the Silverado OEM harness and GM’s ECU Data.
Precise Flow Match. The 775cc injectors all are precisely flow-matched to within 1%, to give uniform performance and fuel delivery to each cylinder. Within every set, each injector is individually numbered, and the results for each injector are listed on a detailed flow sheet included with the set. Additionally, the Fuel Injector Clinic injectors are flow tested and rated at 43.5psi (3Bar) at 90ºF fuel temperature using CF-16B calibration fluid. With their superior short pulse width control and tight manufacturing tolerances, these injectors are easy to tune and will provide your Silverado with great drivability.
Limited 1-Year Warranty. Every injector is covered against failure caused by defects in original manufacture by a full 12-month limited warranty.
Application. The Fuel Injector Clinic 8x775cc injector set fits 2007-2013 Silverado models with V8 engines. The kit includes all o-rings needed to fit the factory application. For aftermarket or other unusual setups, please contact us prior to placing your order to make sure you receive injectors that fit properly. This injector set contains high impedance injectors matched to the saturated injector signal generated by the GM OEM ECU. It is also suitable for use with an aftermarket ECU made or set up for high impedance injectors.

Problem Solver
Originally bought ebay refurbished injectors that did not hold up. These were easy to install, and corrected the truck misfire issues. Also make sure you get the wiring conversion kit as it will save time.
