Show original supplier description
The GM Genuine Parts 12682374 represents brand new, stock LT4 replacement fuel injectors, engineered for high-performance applications. These injectors supersede multiple previous part numbers, including 12650284, 12672374, 12684130, and 12683517, ensuring compatibility and an updated component. The price is quoted per individual injector, and it is important to note that there is no functional difference between "low," "nominal," and "high" versions; all eight injectors must match for proper operation. Designed for GM's Gen V V8 and V6 direct injection engines, these injectors are ideal for high-horsepower builds and E85 conversions. Specific applications include the 2014-2017 C7 Corvette LT1, 2015-2017 C7 Z06 Corvette LT4, 2016-2017 Camaro SS LT1, and 2016-2017 CTS-V LT4. They also fit 2014-2017 Silverado and Sierra models equipped with the 4.3L LV3, 5.3L L83, or 6.2L L86 engines, as well as 2015-2017 Suburban, Tahoe, Yukon, and Escalade models with the 5.3L L83 and 6.2L L86 engines. Adaptors, such as EV6 USCAR pigtails and Denso pigtails, as well as various harnesses like the Denso Injector to EV1 or EV6 (USCAR) Harness, may be required depending on your specific setup. These are sold separately.
