Product Details
The Denso OE Style line focuses on first-time fit and OE-level replacement accuracy. Part number 234-8020 is a downstream oxygen sensor designed for vehicles that require a specific-fit sensor with a 0.701 thread diameter and threaded installation. Denso builds and tests these sensors to strict OE standards, helping maintain accurate exhaust feedback for engine management and emissions control. This part cross-references NTK 24155 for the same application.
Compatible With 2020-2022 Nissan Rogue Sport, downstream; 2017 Nissan Rogue Sport, downstream; 2020 INFINITI QX80, downstream; 2017-2019 INFINITI QX80, downstream; 2017-2019 Nissan Armada, downstream; 2017-2019 Nissan Qashqai, downstream; 2018-2019 Nissan Rogue Sport, downstream; and 2016 INFINITI QX80, downstream. Denso 234-8020 is a direct-fit choice for Nissan Rogue Sport and INFINITI QX80 downstream oxygen sensor replacement needs.
Common Uses
- Replacing a failed downstream oxygen sensor
- Restoring accurate exhaust gas feedback to the engine control system
- Addressing check engine light concerns related to oxygen sensor performance
- Correcting drivability issues caused by an aging or contaminated sensor
- Supporting emissions system maintenance on Nissan and INFINITI models
Installation Notes
Verify the connector style, wire count, thread diameter, and downstream position before installation. This is a specific-fit sensor, so confirm the vehicle year, make, and model against the listed applications for Nissan Rogue Sport, Nissan Armada, Nissan Qashqai, and INFINITI QX80. Use proper exhaust sensor removal practices to avoid damaging the threaded bung or wiring harness.
