Fuel Injector Clinic 1200cc (Previously 1100cc) Fuel Injector Set - High Z (1989-2005 Mazda Miata MX-5 NA/NB) (is601-1200h)
Give your 1989-2005 Mazda Miata MX-5 NA or NB the fuel capacity needed for a serious performance build with the Fuel Injector Clinic 1200cc High-Z Fuel Injector Set. Part number is601-1200h, previously is601-1100h, includes four 1200cc saturated, high-impedance ball and seat injectors engineered to deliver substantial fuel flow without sacrificing the precise control needed for street drivability and accurate tuning. Fuel Injector Clinic's Data Match Technology, superior short pulse width control, and detailed injector characterization make this set an excellent choice for high-performance Miata combinations that demand consistent, predictable fueling.
Fuel Injector Clinic precisely matches the is601-1200h set using its proprietary Data Match Technology. Each injector is individually serial numbered, and the included Data Match Sheet provides detailed flow matching and latency information for the specific injectors in your set. FIC flow tests and rates these injectors at 43.5 PSI (3 Bar) with fuel temperature maintained at 90 degrees F using CF-16B calibration fluid. PGTJETR4Q solder-in pigtails are included, while optional PADPJtoD4 plug-and-play adapters provide an installation option without cutting or soldering the factory wiring harness.

Wiring and Installation
The is601-1200h injector set requires an injector connector change when installed with the included PGTJETR4Q pigtails. The pigtails can be soldered into the vehicle's wiring harness to replace the existing injector connectors. If you prefer to retain the factory wiring harness without cutting or soldering, optional PADPJtoD4 plug-and-play adapters can be used instead.
Fuel Injector Clinic uses brand-new, unused injectors for its performance applications rather than relying on remanufactured or core-program injectors. The injectors are configured with the O-rings required for the listed factory application. If your Miata uses an aftermarket fuel rail or another non-standard fuel system configuration, contact Beefcake Racing before ordering to verify proper injector fitment.
