Grams Performance Mazda Miata NA/NB 1.6/1.8L 550cc Fuel Injectors (Set of 4)

Grams Performance is known for making high-performance fuel injectors. If you're working on a 1990-2005 Mazda Miata, especially if you've upgraded the engine or are planning more power, these 550cc fuel injectors are a solid option to ensure your engine gets the fuel it needs. They are designed to handle more fuel flow than stock, which is crucial when you're pushing an engine beyond its original specifications.

These injectors use a high impedance design, meaning they work with your stock ECU without needing an external resistor box. They come with 11mm top adapters and the necessary lower cushion for the bottom, designed to fit with DENSO-style injectors. You'll need to use the included EV6 pigtails and splice them into your wiring harness, and a fuel rail spacer might be required depending on your specific setup. The set includes four injectors, enough for a complete engine swap.
