High-Flow Multiport Fuel Injector

The GM 12684130 is a genuine GM high-flow multiport fuel injector kit, designed as a factory replacement. These injectors are manufactured in America and are built to perform like original equipment. This listing is for a single injector, with the price reflecting the cost per unit. It is essential to purchase all eight injectors to ensure they match for proper system function. Please note that there is no functional difference between 'low,' 'nominal,' and 'high' versions of these injectors; the key is uniformity across all eight. These injectors are specifically identified as LT4 injectors and are a direct fit for various GM vehicles. They have a 7.5mm stem and are a factory drop-in option for engines like the LT1 to increase fuel delivery, particularly when using E85 or boost. This part supersedes several other GM part numbers, including 12650284, 12672374, and 12683517. Compatibility includes: Chevrolet Corvette (2015-2019, 8 Cyl 6.2L Z06), Cadillac CTS V (2016-2019, 6.2L V8), and Chevrolet Camaro ZL1 (2017-2021, 6.2L V8). It is important to be aware that GM has transitioned from a 7.5mm stem injector to a 6mm stem in some newer models (2022+ Gen V LT), which could be a limiting factor for specific LT4 fuel system upgrades.
