SKP SK25024403 Oxygen Sensor

Overview

The SKP SK25024403 oxygen sensor is a downstream replacement sensor for a wide range of Nissan and INFINITI applications. It is built for vehicles that use a downstream sensor location to monitor exhaust after the catalytic converter, including Nissan Frontier, Pathfinder, Xterra, Maxima, Altima, and 350Z applications.

Use this SKP oxygen sensor when you need a direct-fit replacement for downstream monitoring on compatible Nissan and INFINITI models. The SK25024403 part number appears across multiple fitments, including Nissan NV1500, NV2500, and NV3500 applications.

Key Features

• Downstream oxygen sensor for exhaust monitoring after the catalytic converter
• Compatible with multiple Nissan, INFINITI, and Suzuki applications
• Direct replacement fitment for listed vehicle applications
• Supports downstream right, downstream left, downstream front, downstream rear, and downstream positions where specified
• SK25024403 part number for application matching

Common Replacement Uses

• Replacing a failed downstream sensor that triggers emissions-related fault codes
• Restoring exhaust monitoring on Nissan and INFINITI vehicles with sensor signal issues
• Addressing drivability concerns tied to inaccurate oxygen sensor readings
• Correcting emissions inspection failures caused by a worn sensor

Installation Notes

Confirm the exact downstream position and connector match before installation. Review the vehicle application carefully, especially for models with multiple downstream sensor locations or date-specific fitment such as the 2004 Nissan Altima from 1/2004. The SK25024403 should be matched to the listed application before replacement.

Quality Assurance

SKP offers an OE-style replacement part number for the listed applications. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
