Mercedes-Benz CLK500 Downstream Oxygen (O2) Sensor

SKU CLK500-O2D
Price

$74.99

The downstream oxygen sensor monitors the catalytic converter's efficiency after the exhaust gas passes through it. A failing sensor typically triggers a check-engine light even though the car may drive normally.

Designed for the C209 CLK500's 5.0L V8 M113 exhaust layout, this sensor matches the factory bung location and wiring connector for a bolt-in fit.

Reliable construction ensures accurate catalyst monitoring, helping your car pass emissions checks and keeping the dash light off.

"The socket set is top-tier quality. Heavy-duty steel that handles real torque without slipping. Better than the big box store brands honestly."
