Grams Performance 1600cc Evo X INJECTOR KIT

If you're pushing your 2002-2011 Honda Civic beyond stock power levels, you'll eventually need more fuel. These Grams Performance 1600cc injectors are designed to handle that demand. They're a direct replacement for your stock injectors, but with a much higher flow rate to support significant engine modifications. Accurate fuel delivery is critical for both performance and engine health, especially when you're running more boost or a larger displacement engine.

Grams Performance builds these injectors with stainless steel internals, making them compatible with a wide range of fuels, including oxygenated types like FTW, Q16, and M5. Each injector in the set is individually balanced and flow-tested, then dynamically matched to within one percent of each other. This ensures that every cylinder receives the same amount of fuel, which is key for smooth idling, responsive throttle, and consistent power output across the entire RPM range. The ultra-fast solenoids offer a linear response, meaning they can precisely meter fuel even at very high fuel pressures and short injection durations, which is common in high-performance tuning.

This kit includes a set of four 1600cc injectors. You'll need to use the included EV1 pigtails and splice them into your existing wiring harness, as these injectors use a different connector than the factory ones. Because these are high-flow injectors, they are typically used as part of a larger engine build, so make sure your fuel pump and tuning are also up to the task.
