Denso OE Style Oxygen Sensor 234-8007
Denso 234-8007 is an OE Style heated oxygen sensor built for direct replacement on select Lexus applications. It is engineered for exact fit and stable signal performance, with a threaded mounting design and a 4-wire, male-connector configuration.
Compatible With Lexus IS300, IS350, RC300, RC350, and GS350 downstream right or downstream left positions, depending on model year and engine layout. This part number is a direct-fit option for drivers replacing a worn downstream oxygen sensor on Lexus vehicles.
Key Features
- Heated oxygen sensor for faster operating response
- Specific-fit design for OE-style replacement
- 4-wire configuration with male connector
- Threaded mounting type for direct installation
- 22.83 in. wiring harness length
- 0.709 in. thread diameter
- Built to OE standards for fit and signal consistency
OE Style Construction
Denso’s OE Style line is built to match original equipment requirements for form, fit, and function. The sensor uses an aluminum oxide trap layer to help protect the ceramic element from silicone and lead contamination, supporting long-term sensor performance and accurate exhaust monitoring. If you are replacing a downstream oxygen sensor on a Lexus IS300, IS350, RC300, RC350, or GS350, Denso 234-8007 provides a direct replacement path with the correct connector and mounting style.
This part cross-references NTK 24131 for the same application.
What This Sensor Helps Address
- Check engine light related to oxygen sensor performance
- Incorrect downstream exhaust feedback readings
- Reduced fuel economy caused by a failing sensor
- Slow sensor response after extended heat cycling
- Driveability issues tied to aging emissions components
Installation Notes
Verify the vehicle position before ordering, since this part is listed for downstream right and downstream left applications across different Lexus models and years. Confirm connector style, wire count, and thread size against the original sensor before installation. Use proper oxygen sensor service tools and inspect the exhaust bung threads for damage or contamination before threading in the replacement.
Quality Assurance
Denso manufactures and tests this oxygen sensor to OE standards for direct replacement use. The OE Style design is intended to deliver the correct fit and signal characteristics for the listed Lexus applications, including 2016-2024 Lexus GS350, IS300, IS350, RC300, and RC350 coverage by position.
