FAQs
Do these injectors replace the factory direct injection injectors?
No. The IS834-0850H is designed for BMW N54 and N55 engines equipped with an aftermarket intake manifold or port injection kit. They are intended for supplemental port injection and are not a replacement for the factory direct injection system.
Why does Fuel Injector Clinic include a Data Match calibration sheet?
Each injector is individually tested, flow matched, and assigned a unique serial number. The included calibration sheet provides injector-specific flow and latency data, allowing tuners to achieve more accurate ECU calibration, improved drivability, and consistent fuel delivery across all six cylinders.
