OE Style Construction
Denso’s OE Style sensor line is built and tested to OE-level standards for exact replacement fitment. This product line uses a precision-built design to match the original application, and it incorporates an aluminum oxide trap layer that helps protect the ceramic element from silicone and lead contamination. That construction supports stable sensor operation, improved fuel efficiency, and longer service life in demanding exhaust environments.
This part cross-references Ford CK4Z9G444A and Bosch 16745 for the same application.
What This Sensor Helps Address
- Check engine light related to oxygen sensor performance
