Bosch 13369 Oxygen Sensor - Upstream

Bosch OE Oxygen Sensor for Porsche 911

Bosch Part Number 13369 is a narrow-band heated oxygen sensor built for precise air-fuel-ratio feedback to the ECU. It supports stable combustion control and emissions management for the 1994 Porsche 911, including upstream applications on Late Production and New Body Style vehicles.

Key Features

• Specific-fit Bosch Actual OE Oxygen Sensor for direct application matching
• Narrow-band heated design for quicker closed-loop operation
• Advanced ceramic sensing element for accurate lambda measurement
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• 4-wire harness with oblong male connector and blade terminals
• Metal housing with high-temperature-resistant construction for demanding exhaust conditions
• Wiring harness included for a cleaner replacement setup

Product Details

Bosch 13369 is part of the Actual OE Oxygen Sensor line, which reflects Bosch’s long history of original-equipment oxygen sensor development. This narrow-band heated sensor measures exhaust oxygen content and sends the signal needed for fuel control adjustments, helping the engine management system maintain the correct air-fuel ratio. For Porsche 911 owners servicing upstream sensor locations, Bosch 13369 provides an OE-style replacement built around the same core sensor technology used in factory applications.

This part cross-references Porsche 99360612600 and 99360612601 for the same application.

What This Sensor Helps Address

• Check engine light related to oxygen sensor performance
• Rough idle caused by inaccurate air-fuel feedback
• Fuel mixture issues that affect combustion stability
• Emissions test failures tied to upstream sensor response
• Slow closed-loop transition after startup

Installation Notes

Fits 1994 Porsche 911, Upstream, Late Production; Actual OE Oxygen Sensor. Fits 1994 Porsche 911, Upstream, New Body Style; Actual OE Oxygen Sensor. Confirm connector shape, thread size, and harness routing before installation. Use the threaded mounting point and verify the sensor seats correctly in the exhaust bung. Because this is a heated narrow-band sensor, proper electrical connection is important for accurate signal output.

Quality Assurance

Bosch backs this oxygen sensor with more than five decades of OE development and aftermarket supply experience. The Actual OE Oxygen Sensor line is built to deliver OE-proven fit, signal accuracy, and durability under heat and vibration.
