Walker Products 250-21036 Oxygen Sensor Direct Fit Narrow-Band

The Walker Products 250-21036 is a direct-fit narrow-band oxygen sensor engineered as an OEM replacement for specific vehicle applications. This sensor monitors exhaust oxygen levels and provides critical feedback to the engine control unit (ECU) for optimal fuel mixture control, emissions regulation, and engine performance.

Key Features:

• Direct-fit design for specific vehicle applications—no modifications required
• Narrow-band technology for precise air/fuel ratio monitoring
• OEM-equivalent quality and performance specifications
• Manufactured to ISO9001/TS 16949 automotive quality standards
• Application-specific construction for proper fitment position and ECU communication

A failing oxygen sensor can trigger check engine lights, reduce fuel economy, increase emissions, and cause poor engine performance. This Walker Products sensor restores proper ECU feedback for improved drivability and compliance with emissions standards. Always inspect wiring harnesses and connectors for damage during installation to ensure optimal sensor performance and longevity.
