Overview
The Fuel Injector Clinic 525cc High-Z Injector Set is built using high impedance Bosch core injectors designed for 2007-2013 Chevrolet and GMC trucks and SUVs equipped with 4.8L, 5.3L, or 6.0L Vortec V8 engines. These injectors utilize the latest technology to provide excellent linearity and short pulse width repeatability for smooth drivability and straightforward tuning.
Each set of eight injectors is precisely flow matched to within 1%. Individual results are listed on a detailed flow sheet included with the set, and every injector is numbered. The injectors feature drop-in plug fitment for the factory application, which may require the provided fuel rail spacers. Fuel Injector Clinic includes all necessary o-rings.
Fuel Injector Clinic provides plug-and-play GM ECU data, and Max Redline can tune your car for the new injectors via log-based remote tuning or in-shop service. Tuning is required after installing larger injectors. This item includes free shipping and is backed by a lifetime warranty against manufacturer defects.
