Bosch Oxygen Sensor P/N:13642

Feed the ECU clean, accurate air-fuel data with the Bosch Switching-Type Oxygen (O2) Sensor 13642, a narrow-band heated sensor that installs as a direct-fit replacement across a range of late-1990s and early-2000s Mercedes-Benz models — including the 1998-2000 CL500 [V8-5.0L], 1998-2000 E320 [V6-3.2L], and 1996-2000 S500 [V8-5.0L]. It measures oxygen in the exhaust stream and reports the air-fuel ratio back to the ECU for closed-loop fuel control, helping keep combustion stable and emissions in check.

• Precise switching feedback: delivers air-fuel-ratio signals to the ECU for accurate fuel trim across a wide range of operating conditions.
• Narrow-band heated design: an integrated heater reaches operating temperature in under 10 seconds for quick closed-loop operation.
• Durable build: steel housing, advanced ceramic element, and TSP coating, rated for exhaust streams up to 1,880°F to resist vibration and corrosion.
• Ready to install: direct-fit connector with pre-applied conductive anti-seize on the threads; wiring harness included, mounting bracket not included.

Specs: 4-wire female round connector, threaded M18-1.5 mount, 22 mm hex, with an approximately 15.7 in wiring harness. Engineered to meet or exceed OE specifications. This sensor is cataloged for upstream and downstream positions (including upstream left and right) depending on the application. Quantity varies by application — some listed vehicles use two sensors and others use one; sold individually. Country of origin: United States. Additional applications include the 2000 E430 [V8-4.3L], 1997-1999 S320 [L6-3.2L], 1996-1999 S420 [V8-4.2L], 2000 S430 [V8-4.3L], 1997 SL320 [L6-3.2L], and 1999-2002 SL500 [V8-5.0L]; see the Buyer's Guide tab for the full list. Manufacturer part number 13642.
