FAQs
Do these injectors replace the factory direct injection injectors?
No. The IS834-1200H-D 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 do not replace the factory direct injection system.
What makes Fuel Injector Clinic's Data Match Technology different?
Every 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 calibration, improved drivability, and consistent fuel delivery across all six cylinders.
