DeatschWerks 06+ Miata 550CC Top Feed Injectors

Upgrade your Mazda Miata fuel system with the DeatschWerks 18U-00-0550-4 550cc injector set. This matched set of 4 injectors is designed for 2006-2015 Mazda Miata / MX-5 applications and is commonly used for turbo builds, supercharged setups, naturally aspirated performance builds, and other tuned fuel system upgrades.

DeatschWerks lists these injectors with a 550 cc/min flow rate and USCAR connector shape. The set is matched for consistent fuel delivery across all 4 cylinders, making it a solid option for modified NC Miata builds that need more fuel flow than the factory injectors can provide.

These injectors are intended for properly tuned applications and should not be installed on a factory stock ECU calibration.

Important Fitment, Tuning & Emissions Note

These injectors require proper ECU calibration / tuning before use. Do not install larger injectors on a factory stock tune.

Confirm injector connector type, fuel rail compatibility, O-ring fitment, intake manifold clearance, ECU setup, fuel pressure, fuel pump capacity, and tuning software compatibility before ordering.

Some setups may require injector plug adapters, wiring changes, or fuel system changes depending on the existing harness, ECU, and supporting modifications.
