What does a 550cc fuel injector do for my Miata?

A 550cc fuel injector can deliver more fuel than your stock injectors. This is often needed to support performance modifications like forced induction or engine tuning that require a greater fuel supply.

Do these injectors require any special wiring or adapters?

No, these injectors feature a high impedance design and come with a 14mm top adapter and EV6 pigtail, making them a plug-and-play replacement that doesn't require additional adapters or a resistor box.
