Mopar Performance 68203458AA Upstream Left Oxygen Sensor 6-Pin

The Mopar Performance 68203458AA is a genuine OEM oxygen sensor designed as a direct factory replacement for select Chrysler, Dodge, and Jeep vehicles equipped with the 6.2L supercharged HEMI V8 engine. This sensor is positioned on the left side, upstream before the catalytic converter, and plays a critical role in monitoring exhaust gas oxygen content to optimize engine performance and fuel efficiency.

Key Features:

• Genuine Mopar OEM quality ensures precise fit and reliable performance
• 6-pin connector design with factory clips for easy installation and swap-out
• Left side upstream placement (before catalyst)
• Designed for 6.2L supercharged HEMI V8 SRT engines
• Direct replacement for worn or damaged oxygen sensors
• Helps maintain proper air-fuel ratio and emissions compliance

This oxygen sensor is essential for proper engine operation, as the PCM (Powertrain Control Module) relies on accurate oxygen sensor data to adjust fuel delivery. When oxygen sensors fail, the PCM may set diagnostic trouble codes and revert to open-loop fuel control, reducing performance and fuel economy. Using genuine OEM parts ensures your vehicle maintains factory specifications and performance standards.

Note: Oxygen sensors are sold individually. The corresponding right-hand sensor is part number 68250166AA.
