Fuel Injector Clinic 2150cc Fuel Injector Set - High Z (1989-2005 Mazda Miata MX-5 NA/NB) (is601-2150h)
Fuel a serious high-horsepower 1989-2005 Mazda Miata MX-5 NA or NB build with the Fuel Injector Clinic 2150cc High-Z Fuel Injector Set. Part number is601-2150h includes four massive 2150cc saturated, high-impedance injectors engineered to deliver the fuel volume required by demanding performance combinations while retaining exceptional low-speed control. These injectors are particularly well suited to E85 and other high-volume fuel applications, with Fuel Injector Clinic's Data Match Technology helping provide the precise, predictable injector operation tuners need at both high flow rates and short pulse widths.
Because of their exceptionally high flow rate, Fuel Injector Clinic uses dynamic Data Match Technology when producing the is601-2150h injector set. This matching significantly improves ECU control in the sub-2ms pulse width range commonly encountered during idle and part-throttle operation. Each injector is individually serial numbered, and the included Data Match Sheet provides detailed flow matching and latency information. 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.

Important Fuel Compatibility Warning
Do not use the is601-2150h injectors with VP Import, Q16, or other MTBE oxygenated fuels. The internal construction of the 2150cc injector includes a seal that can swell when exposed to MTBE. This swelling can significantly reduce injector flow, making these injectors unsuitable for MTBE oxygenated fuels.
The 2150cc injector is suitable for E85 applications, but proper care is important when using alcohol-based fuels. Prolonged disuse while alcohol-based fuel remains in the injectors can create potential corrosion concerns. Follow Fuel Injector Clinic's care instructions when operating and storing a vehicle using E85 or other alcohol-based fuels.
Massive Fuel Flow With Precise Low-Speed Control
The challenge with an injector this large is not simply delivering enough fuel at wide-open throttle. Precise control at low pulse widths is critical to maintaining usable idle and part-throttle behavior. Fuel Injector Clinic's dynamic Data Match process is designed to improve ECU control in the sub-2ms range, helping the is601-2150h deliver the combination of massive flow capacity, tunability, and drivability required by extreme-performance Miata builds.
Installation
Fuel Injector Clinic uses brand-new, unused injectors for its performance applications rather than relying on remanufactured or core-program injectors. The is601-2150h 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.

FAQs
Can Fuel Injector Clinic is601-2150h injectors be used with E85?
Yes. The 2150cc injectors are well suited to E85 and other compatible high-volume fuel applications. However, Fuel Injector Clinic warns of potential corrosion issues from prolonged disuse while the injectors are exposed to alcohol-based fuels, so the manufacturer's care instructions should be followed.
Can the is601-2150h injectors be used with Q16 or VP Import?
No. Do not use these injectors with Q16, VP Import, or other MTBE oxygenated fuels. MTBE can cause an internal seal to swell, resulting in a significant reduction in injector flow.
