Grams Performance 02-11 Subaru WRX / 07+ STI / 07-11 Legacy 550cc Fuel Injectors (Set of 4)

This kit gets you a set of four 550cc fuel injectors from Grams Performance, designed to replace the stock injectors in your Subaru. These are high impedance injectors, meaning they'll work with your car's factory wiring with the addition of a wire splice. The kit includes DENSO lower cushion bottoms and EV6 pigtails, and you'll need to splice the wiring to connect them.

Grams Performance uses advanced manufacturing techniques and premium materials to build these injectors. They are a popular choice for Subaru owners looking to upgrade their fuel system for better performance. The 550cc flow rate is a notable step up from stock, allowing for more fuel to be delivered to the engine, which is often necessary when making other performance modifications like turbo upgrades or engine tuning. This improved fuel delivery can help your engine run more efficiently and safely under increased load.

Keep in mind that these injectors are not CARB approved and cannot be shipped to California. You'll need to splice the wiring to install them, so be prepared for that step in the installation process.
