OE Style Construction
Denso’s OE Style line focuses on exact replacement fit and factory-style performance. This oxygen sensor is precision built to match the original application, helping maintain proper exhaust feedback for engine management on Dodge Dakota, Dodge Durango, and Ram platform vehicles. The sensor also uses an aluminum oxide trap layer to help protect the ceramic element from silicone and lead contamination, supporting long service life and stable operation.
This part cross-references Bosch 13664 and NTK 23135 for the same application.
What This Oxygen Sensor Helps Address
- Check engine light concerns related to oxygen sensor performance
- Incorrect air-fuel ratio feedback from a worn upstream sensor
- Reduced fuel economy caused by slow or inaccurate exhaust readings
- Rough idle or drivability issues tied to faulty sensor input
- Emissions test failures caused by degraded sensor response
