Grams Performance 1150cc Evo X INJECTOR KIT

The stainless steel internals in these Grams Performance 1150cc injectors are built to handle a wide variety of fuels, including high-performance options like FTW, Q16, and M5. When you're pushing your engine's limits, accurate fuel delivery is critical, and these injectors are designed to provide that precision. They're a popular choice for tuners looking to upgrade the fuel system on their 2002-2011 Honda Civic.

Each injector in this set of four is individually balanced and flow tested, then dynamically matched to within one percent of each other. This attention to detail ensures consistent fuel delivery cylinder-to-cylinder, which helps maintain smooth idle quality and improves throttle response, especially at lower engine speeds and with short fuel pulse widths. The ultra-fast solenoids offer a linear response across many operating conditions, meaning they can accurately meter fuel even when dealing with high fuel pressures and very short injection times.

This kit includes a black bottom adapter and EV1 pigtails, but you will need to splice wires for installation. Because these are high-performance parts, they are not CARB approved and cannot be shipped to California. If you're building a high-output engine, these injectors are a solid option for ensuring your fuel system can keep up.
