550cc - Miata

Swapped out my stock injectors for these 550cc units and the difference in throttle response was immediate. The matched set made installation straightforward and the fuel delivery feels perfectly consistent through the whole RPM range.

My 2008 Miata idles so much smoother now with these 550cc injectors—the fuel delivery feels consistent even during hard cornering. The plug-and-play installation made the swap straightforward, and I'm already noticing better throttle response.

Dropped these into my 2010 Miata over the weekend and the idle smoothed right out, no more stumble when cold. The matched set makes a real difference, fuel delivery feels consistent across all four cylinders.
