FIC Injectors - NA/NB Miata

Fuel Injector Clinic injectors for the NA and NB Miata, whether it's a built naturally aspirated engine, E85, or more power than you know what to do with. I've used FIC injectors for years without a single failure. Every set comes with serialized flow data, so you know exactly what you're putting in the engine and setting up the injectors in a standalone ECU is easy.

If you're building your own wiring harness, the injectors come with flying lead pigtails that have the correct connector. If you want plug and play, choose the plug and play harness option, and they'll come with harnesses already terminated that plug into the stock Miata harness.

These fit NA and NB Miatas only. I've tested them with the stock intake manifold, the square top, the Skunk2 and the new ChathamCNC manifold, and they fit every one without changing top hats.

As a rough guide, 365cc suits naturally aspirated and E85 builds, 445cc to 650cc suits supercharged builds, and 775cc to 1000cc suits turbo builds up to 450 horsepower. 1200cc and up is for very high horsepower builds. Expect idle issues at that size, and 1990 to 1993 Miatas need the sequential injection mod.
