Fitment gate — the M11 and ISM platform ran across several engine control module generations, and injectors are not common to all of them. Read the part number off the injector you are removing and match it before ordering, and confirm your engine serial number and CPL.

Second fitment gate — this is a Celect-family electronic unit injector. It is not a common rail injector and will not fit engines using a common rail fuel system. Confirm your fuel system type before ordering.
