OE Style Construction
Denso’s OE Style line is built to match original equipment requirements for fit and function. The sensor uses a precision-built design intended to replace the factory unit without modification, while the aluminum oxide trap layer helps protect the ceramic sensing element from silicone and lead contamination. That protection supports stable engine management, fuel control, and long service life in demanding exhaust conditions.
This part cross-references Bosch 13959 and NTK 24417 for the same application.
