Grams Performance 1600cc Miata NA/NB/ 1.6/ 1.8 INJECTOR KIT

If you're looking to significantly upgrade the fuel system on your 1990-2005 Mazda Miata, especially for boosted or high-performance builds, a larger injector set is a critical step. These Grams Performance 1600cc injectors are designed to deliver the precise amount of fuel your engine needs when it needs it, ensuring optimal combustion and power output.

Grams Performance builds these injectors with stainless steel internals, making them compatible with a wide range of fuels, including oxygenated options and race fuels. Each injector is individually tested and matched to within one percent of each other. This attention to detail means you get consistent cylinder-to-cylinder fuel delivery, which is key for a smooth idle, responsive throttle, and maximum power, even at very short injection durations. The solenoids are also very fast and precise, offering a linear fuel response across different engine loads and speeds, which helps maintain drivability even with such high flow rates.

This kit includes four 1600cc injectors, each with an 11mm top adapter and a black bottom adapter. You'll need to splice wires for the included EV1 pigtails, but they are designed to work with a fuel rail spacer for a straightforward installation. Keep in mind these are not CARB approved and cannot be shipped to California.
