Grams Performance Nissan 300ZX (Top Feed Only 14mm) 550cc Fuel Injectors (Set of 6)

If you're working on a 1990-1996 Nissan 300ZX and looking to upgrade your fuel system, these 550cc top feed fuel injectors from Grams Performance are a solid option. They are designed to replace your stock injectors and deliver more fuel to the engine, which is often necessary when you've made other performance modifications like intake or exhaust work, or if you're planning on tuning the engine for more power. This set includes six injectors, matching the cylinder count of your 300ZX.

These injectors use a high impedance design, meaning they work with your stock wiring and ECU without needing a separate ballast resistor, simplifying the installation process. They feature a 14mm top adapter and an EV6 connector, and while they are designed to fit directly, you will need to splice the wiring to connect them. Grams Performance uses advanced manufacturing techniques and premium materials to ensure these injectors are well-built and reliable for performance applications. They are rated at 550cc per minute, providing a significant increase in fuel flow over stock, which is crucial for supporting higher horsepower levels.

Keep in mind that these injectors are not CARB approved and cannot be shipped to California. You'll also want to ensure your engine management system is tuned to take advantage of the increased fuel capacity these injectors offer. This upgrade is a key step for anyone looking to push their 300ZX's performance further.
