Show original supplier description
The Lingenfelter NOSTRUM GM GEN V Stage 2 Fuel Injectors represent a substantial upgrade for performance-oriented GM Gen V applications, including Corvettes, Camaros, CTS-Vs, trucks, and SUVs. These injectors are designed to provide a significant increase in fuel delivery, boasting a 75% flow increase over stock LT1/L86 and a 51% increase over stock LT4. Engineered for maximum power potential, these injectors can support up to 1400 wheel horsepower on gasoline or around 1000 wheel horsepower on E85, all while maintaining an OEM equivalent spray pattern. This precise spray pattern is crucial for optimal fuel atomization, homogenous air-fuel mixtures, improved combustion quality, and preventing issues like oil dilution and increased knock propensity. Each injector is individually tested and dynamically batched into sets with minimal variance for consistent performance. They are fully controllable by the factory engine management system and are ethanol compatible. Tuning is required for optimal performance, with HP Tuners and EFILive recommended tuning suites. The injectors operate at a maximum recommended pressure of 200 Bar. Fitment includes a range of GM vehicles: 2020-2021 Chevrolet C8 Corvette (vehicles must confirm not using 6mm stem injectors), 2014-2019 Chevrolet C7 Corvette (including Z06), 2014-2023 Chevrolet Silverado/GMC Sierra (2021+ vehicles must confirm not using 6mm stem injectors), 2014-2023 Chevrolet Tahoe/Suburban & Cadillac Escalade (2021+ vehicles must confirm not using 6mm stem injectors), 2016-2022 Chevrolet Camaro SS, 2017-2023 Chevrolet Camaro ZL1, and 2016-2019 Cadillac CTS-V. A limited lifetime warranty is provided by Nostrum High Performance.
