Grams Performance 02-11 Subaru WRX / 07+ STI / 07-11 Legacy 1150cc Fuel Injectors (Set of 4)

Grams Performance is known for making high-performance fuel injectors for vehicles that demand more. If you're working on a 1991-2014 Subaru Legacy, 2002-2011 Impreza, 2004-2013 Forester, or a 2007+ STI, these 1150cc injectors are a solid option for upgrading your fuel system. Fuel injectors are critical for getting the right amount of fuel into your engine, and these are built to handle demanding performance applications.

These injectors feature stainless steel internals and can handle all types of fuel, including oxygenated fuels like FTW, Q16, M5, and C45. Grams Performance modifies these for high-performance use, and each injector is individually balanced and flow-tested. They are dynamically matched within one percent of each other, which means you get consistent cylinder-to-cylinder performance, even when the engine is running at low pulse widths. This consistency helps maintain a smooth idle, improves throttle response, and generally makes the engine run better overall. The solenoids are ultra-fast and precise, offering a linear response curve across a wide range of operating conditions, meaning they can accurately meter fuel even at high pressures and very short pulse widths.

This set includes four injectors, each with an 11mm top adapter, a Denso lower cushion, and an EV1 pigtail. You will need to use a fuel rail spacer and splice wires for installation. Please note that these are not CARB approved and cannot be shipped to California.
