Grams Performance 550cc Sentra SE-R QR25DE Injector Kit

If you're looking to get more out of your 1991-1994 or 2002-2006 Nissan Sentra, especially if you've modified the engine for better performance, upgrading your fuel injectors is a smart move. These 550cc injectors from Grams Performance are designed to deliver more fuel than stock, which is crucial for supporting increased airflow from engine modifications like turbochargers or performance camshafts. They are a high impedance design, meaning they work with your car's stock ECU without needing a separate injector driver box.

Grams Performance uses advanced manufacturing techniques and premium materials to build these injectors. This means you can expect them to be well-built and reliable for consistent fuel delivery. The kit includes a set of four injectors, and they come with EV6 pigtails, though you will need to splice the wiring to connect them to your Sentra's harness. This is a common step when upgrading injectors to a different style or flow rate.

Keep in mind that these injectors are not CARB approved and cannot be shipped to California. For other states, they offer a solid option for tuning your Sentra's fuel system to match your performance goals.
