URO 9A260618802 Oxygen Sensor Pre-Catalytic Converter

The URO 9A260618802 is a direct-fit replacement oxygen sensor designed for European vehicles, specifically Porsche applications. This sensor is positioned before the catalytic converter in the exhaust manifold, where it measures the amount of unburned oxygen in the engine's exhaust gases. Based on these readings, the sensor sends signals to the engine control unit, which adjusts the air/fuel mixture for optimal engine performance, fuel efficiency, and emission control.

Key Features:

• Direct-fit OE replacement design for precise fitment and function
• Pre-catalytic converter location (upstream sensor)
• Manufactured using high-quality materials engineered to withstand intense exhaust system heat
• Plug-and-play connection with OE-specified connectors for easy installation
• Alloy conductors minimize electrical resistance for accurate sensor operation
• Meets or exceeds OEM specifications for reliable performance

Cross-Reference Information:

OEM Part Number: 9A2-606-188-02, 9A2.606.188.02. This sensor is manufactured by Bosch (Bosch part number 0258017527) and offered by URO Parts as a quality aftermarket alternative to the genuine Porsche component.

Why Replace Your Oxygen Sensor:

A faulty oxygen sensor can cause excessive fuel consumption (up to 30% fuel waste), driveability problems such as engine surging or hesitation, high hydrocarbon emissions, illuminated check engine lights, and mixture-related fault codes. When completely failed, it may cause catalytic converter damage due to overheating. Regular oxygen sensor replacement helps maintain proper engine function and prevents costly repairs.
