Walker Products Universal Oxygen Sensor Narrow-Band

The Walker Products Universal Oxygen Sensor (Narrow-Band) is an O2 sensor, also called an oxygen sensor or lambda sensor. It measures the oxygen content of the exhaust gas and sends that feedback to the engine control system. The engine computer uses the signal to fine-tune the air-fuel mixture. That helps the engine run efficiently and keeps emissions down.

Key Features:

• OE-based design: Built for reliable, original-equipment-style performance and efficiency.
• Platinum-coated electrodes: A gas-permeable platinum layer gives fast, accurate, consistent oxygen sensing.
• Protective coating: It helps prevent contamination and erosion of the electrode surfaces from combustion residue and exhaust particulates, which extends sensor life.
• Better fuel control: Accurate oxygen readings help optimize combustion efficiency and fuel economy.
• Emissions monitoring: It monitors exhaust gases to help reduce pollutants.
• Universal-style design: The sensor is designed to be adapted to the vehicle's wiring connection during installation.

Walker Products is a long-established name in exhaust and engine management components. A fresh narrow-band oxygen sensor can help restore throttle response and fuel economy, and it can clear sensor-related check engine lights.
