GM Perfomance Gen V LT4 Fuel Injectors - 140LB @ 2,950 psi

Keep pace with the fuel demands of a boosted or built Gen V engine with the Genuine GM 19420801 LT4 fuel injector kit. Engineered from the factory for the supercharged LT4, these OEM direct-injection injectors flow more than stock LT1, L83, and L86 injectors — which is exactly why they've become a go-to upgrade for supercharged, turbocharged, and large-displacement stroker builds.

Please Note: For those making the jump from the L83/L86/LT1 fuel system, DI fuel injectors are designed to best atomize the fuel at specific pressures related to the corresponding GM mechanical fuel pump so we do not recommend swapping the lt4 pump or injectors individually but rather treat them as a combined unit.

*Notice, Tuning is required for non-LT4 applications!
