Grams Performance Scion TC / XB / Toyota 1ZZ/2ZZ/3SGTE 550cc Fuel Injectors (Set of 4)

Grams Performance is known for making high-performance fuel injectors. If you're working on a 2003 or 2004 Toyota Corolla, these 550cc fuel injectors are a solid option for improving your engine's fuel delivery. They are designed with an 11mm top adapter and a DENSO lower cushion bottom, ensuring a good seal.

These injectors are built using advanced manufacturing techniques and premium materials, which Grams Performance uses across their line of performance parts. They feature a high impedance design, meaning they'll work with your factory ECU without needing a separate ballast resistor. This set includes four injectors, enough to replace all the injectors on your four-cylinder engine. Keep in mind that a wire splice will be required for installation, so be prepared for that step.
