APW Warehouse Supplies AP4-396 Oxygen Sensor

The APW Warehouse Supplies AP4-396 is a direct-fit oxygen sensor designed to replace OEM sensors in a variety of vehicle applications. This sensor monitors the oxygen content in exhaust gases and sends data to the vehicle's engine control module (ECM) to optimize air-fuel mixture for proper combustion, fuel efficiency, and emissions control.

Key Features:

• Direct-fit replacement oxygen sensor for simplified installation
• Precision-engineered sensing element for accurate readings
• Durable construction designed to withstand high exhaust temperatures
• Helps maintain optimal fuel economy and engine performance
• Meets or exceeds OEM specifications for reliable operation
• Pre-wired connector for plug-and-play installation on compatible vehicles

Oxygen sensors are critical emissions components that should be replaced when they fail to maintain proper engine performance and meet emissions standards. A faulty oxygen sensor can cause increased fuel consumption, rough idle, and check engine light illumination.
