Grams Performance 1150cc Cobalt INJECTOR KIT

If you're looking to significantly increase the fuel flow for your 2005-2010 Chevrolet Cobalt, especially for a modified engine build, a set of high-performance fuel injectors is a critical component. These 1150cc injectors from Grams Performance are designed to deliver more fuel accurately, which is essential for supporting increased horsepower and maintaining proper engine operation under demanding conditions.

Grams Performance builds these injectors with stainless steel internals, making them compatible with a wide range of fuels, including oxygenated types and racing fuels like FTW, Q16, and M5. Each injector is individually tested and matched to within one percent of each other for flow rate. This attention to detail ensures consistent fuel delivery across all cylinders, which helps maintain a smooth idle, improves throttle response, and allows for precise tuning, even at very short injection durations and high fuel pressures. The solenoids are designed for a linear response, meaning they behave predictably across different operating conditions and fuel pressures.

This kit includes four 1150cc injectors, each with a black bottom adapter and an EV1 connector. You will need to splice wires to connect them to your existing harness. While these injectors offer substantial fuel flow, remember they are not CARB approved and cannot be shipped to California. For optimal performance, these injectors should be paired with a compatible engine management system that can be tuned to take full advantage of their increased capacity.
