Bosch Oxygen Sensor P/N:13642

Keep precise air-fuel feedback flowing to your engine computer with the Bosch 13642 Oxygen Sensor, a premium switching-type Bosch sensor that sends accurate air-fuel-ratio measurements to the ECU for stable combustion control and helps reduce emissions across a wide range of operating conditions. It is listed for several models from one make, among them the 1999-2002 Mercedes-Benz SL500, 1998-2000 Mercedes-Benz CL500 and 1998-2000 Mercedes-Benz E320. See the Buyer's Guide tab for the full list and engine details. The sensor is cataloged for upstream, downstream, upstream left and upstream right positions, depending on the application.

Bosch introduced the original thimble-type oxygen sensor in 1976 and later developed planar narrowband designs for faster light-off, improved lambda accuracy and quicker closed-loop operation. Every Bosch O2 sensor draws on more than five decades of supplying vehicle manufacturers.

• Precise feedback: Delivers air-fuel-ratio signals to the ECU, which helps support efficiency and lower emissions.
• Built for heat: Built to withstand exhaust streams up to 1,880°F. It uses stainless steel housings, integrated heater elements, advanced ceramic elements and TSP coating to resist vibration and corrosion.
• Fast response: Designed to reach operating temperature in under 10 seconds. The ECU gets a usable signal quickly and can enter closed-loop control sooner after a cold start.
• Easy install: Direct-fit connectors, with conductive anti-seize pre-applied to the threads.

Bosch covers this sensor with a 1-year, unlimited-mileage warranty for non-commercial passenger cars and light trucks.
