FAQs
Can these injectors replace the factory direct injection injectors?
No. The IS833-0850H is designed for BMW S58 engines equipped with an aftermarket intake manifold or port injection kit. It is intended for supplemental port injection and is not a replacement for the factory direct injection system.
Why is Fuel Injector Clinic's Data Match Technology important?
