Grams Performance Nissan 240sx/S13/S14/S15/SR20 (Top Feed 14mm) 1150cc Fuel Injectors (Set of 4)

When you're looking to get the most out of your performance engine, the fuel injectors are a critical component. This set includes four Grams Performance 1150cc fuel injectors, designed specifically for top-feed applications with 14mm inlets. These injectors are built with stainless steel internals, making them compatible with a wide range of fuels, including oxygenated types like FTW, Q16, and C45. They are also high-impedance, which helps with precise fuel metering, especially at lower pulse widths.

Grams Performance puts these injectors through rigorous testing. Each one is individually balanced and flow-tested, then matched within one percent of each other. This ensures unmatched cylinder-to-cylinder consistency, which translates to a smoother idle, better throttle response, and more reliable performance across various operating conditions. The solenoids are designed for ultra-fast and precise operation, maintaining linear response even at high fuel pressures and short pulse widths.

This kit comes with the injectors, black bottom adapters, and EV1 pigtails. Please note that a wire splice will be required for installation, and these injectors are not CARB approved, meaning they cannot be shipped to California. If you're rebuilding your top end or looking for a significant fuel system upgrade, this set offers a well-built solution for accurate and consistent fuel delivery.
