Compatibility & Fitment

Fitment gate — this is the code BI injector, covering the 175 to 250 HP ratings. Engines rated 250 to 340 HP use the code BN injector, which is a different part. Read the code off the injector you are removing and confirm it is BI before ordering.

Second fitment gate — engine serial number range is 1,125,228 to 1,999,999. Confirm your ESN falls within that range before ordering a full set.

Installation note — HEUI injectors depend on correct high-pressure oil supply. A failing high-pressure oil pump produces symptoms similar to failed injectors, so confirm the oil system before condemning the injectors.
