Fuel Injector Clinic 525cc High-Z Fuel Injector Set (is115-0525h) - Honda B / H / D Series Except D17
Upgrade the fuel system on your Honda B, H, or D Series build with the precision and consistency of the Fuel Injector Clinic 525cc High-Z Fuel Injector Set. Part number is115-0525h includes four 525cc/min saturated, high-impedance ball-and-seat injectors engineered for Honda B Series, H Series, and D Series applications except the D17. Modern injector technology delivers excellent linearity and short pulse width repeatability, giving performance Honda combinations increased fuel capacity while maintaining the precise control needed for smooth idle, responsive part-throttle operation, and strong drivability.
Fuel Injector Clinic precisely flow matches each is115-0525h injector set to within 1 percent. Every injector is individually numbered, and the results for each injector are documented on the detailed flow sheet supplied with the set. FIC flow tests and rates its high-performance injectors at 43.5 PSI (3 Bar) using CF-16B calibration fluid maintained at 90 degrees F. Superior short pulse width control and tight manufacturing tolerances give tuners a consistent foundation for accurate calibration while helping deliver predictable performance throughout the operating range.

FAQs
What applications does the Fuel Injector Clinic is115-0525h injector set fit?
Part number is115-0525h is designed for Honda B Series, H Series, and D Series engine applications, excluding the D17. Because modified Honda builds can use different fuel rails, intake configurations, and wiring setups, verify fitment before ordering if your fuel system differs from the intended application.
Do the is115-0525h injectors require a wiring connector change?
Yes. The set includes PGTUSC4 solder-in pigtails that can be used to replace the existing injector connectors. For compatible applications, optional PADPUtoJ4 plug-and-play adaptors are available for OBD1 harnesses and PADPUtoH4 adaptors are available for OBD2 harnesses, allowing the connector conversion without cutting or soldering the factory harness.
