Bosch 993-606-116-01 Oxygen Sensor Sensor Heated - O2 4-Wire

The Bosch 993-606-116-01 (also known as Bosch 13721) is a premium OE-type heated oxygen sensor designed for precise exhaust gas monitoring and optimal engine performance. This sensor plays a critical role in measuring oxygen concentration in exhaust gases, allowing the engine control unit to fine-tune the air-fuel mixture for maximum efficiency, reduced emissions, and improved fuel economy.

Key Features:

• 4-wire heated thimble-type sensor with fast-acting heating element for quick operation
• 18mm thread diameter with pre-coated anti-seize compound for easy installation
• 33-inch (838mm) wire length with OE-type direct-fit connector
• Zirconium ceramic sensing element for accurate, reliable readings
• Double laser-welded stainless steel body that is fully submersible and sealed against exhaust contamination
• 100% functionally tested at 1,000°C to ensure quality and longevity
• Upstream/front oxygen sensor position (before catalytic converter)

Bosch invented the automotive oxygen sensor and remains the world's leading OEM supplier. Each sensor undergoes rigorous quality testing to meet or exceed original equipment specifications. A worn or faulty oxygen sensor can lead to poor fuel economy, increased emissions, catalytic converter damage, and rough engine performance. Regular replacement helps maintain optimal engine efficiency and emissions compliance.
