Grams Performance 1600cc 02-11 WRX/ 07+ STi/ Forester XT/ 07-11 Legacy INJECTOR KIT

These Grams Performance 1600cc fuel injectors feature stainless steel internals, making them compatible with a wide range of fuels, including oxygenated options like FTW, Q16, M5, and C45. When you're pushing your engine hard, accurate fuel delivery is critical. These injectors are designed to precisely meter and atomize fuel, which is essential for optimal performance, especially in modified vehicles. They are high-impedance injectors, modified for high-performance use, and each one is individually balanced and flow-tested to ensure they match within one percent of each other.

This cylinder-to-cylinder consistency is a big deal. It means your engine runs smoother, idles better, and responds more predictably, even when you're using very short fuel pulse widths. The solenoids in these injectors are ultra-fast and offer a linear response across many different operating conditions. This precision allows them to accurately deliver fuel even at high pressures and with the shortest pulse widths, which is crucial for tuning and maximizing power output.

This kit includes a set of four 1600cc injectors, each with a 16mm top adapter and a DENSO lower cushion bottom. You'll need to use a fuel rail spacer and splice the included EV1 pigtails to connect them to your wiring harness. Please note that these injectors are not CARB approved and cannot be shipped to California.
