Important Condition Disclosure

Minor Injector Electrical Connector Damage

There may be a small crack in the plastic electrical connector housing of one injector.

This is believed to be a minor physical defect affecting the connector housing rather than the injector’s internal operating mechanism.

The injector was reportedly functioning properly before removal despite this condition.

• One injector connector may have a small crack.
• The affected plastic connector or housing may require repair or replacement.
• Replacement connector components may be available in the aftermarket, subject to compatibility.
