Grams Performance Nissan 240sx/S13/S14/S15/SR20 (Top Feed 11mm) 1150cc Fuel Injectors (Set of 4)

When you're looking to get the most out of your performance Nissan, especially if you've upgraded your engine's breathing capabilities, you need fuel injectors that can keep up. This set from Grams Performance includes four 1150cc top-feed injectors, designed specifically for performance applications. They feature stainless steel internals, making them compatible with a wide range of fuels, including oxygenated and racing fuels like FTW, Q16, and M5. Each injector is individually balanced and flow-tested, then dynamically matched within one percent of each other. This ensures consistent cylinder-to-cylinder fuel delivery, which is crucial for optimal idle quality, throttle response, and overall engine performance, especially at low pulse widths and high fuel pressures.

The advanced solenoids in these Grams Performance injectors are built for ultra-fast and precise operation. They offer a linear response curve across a broad spectrum of operating conditions, meaning they can accurately meter fuel even when the engine computer is asking for very small amounts of fuel or when fuel pressure is high. This level of control is essential for fine-tuning a performance engine and achieving the best possible results. The high-impedance design also contributes to their precise operation and compatibility with modern engine management systems.

This set is a direct fit for the specified Infiniti G20 models. Remember that these injectors are not CARB approved and cannot be shipped to California. For optimal performance, it's recommended to have your engine's fuel maps professionally tuned after installing these higher-flow injectors to take full advantage of their capabilities.
