Bosch 997-606-168-02 Wideband Oxygen Sensor Pre-Catalyst

The Bosch 997-606-168-02 is a premium original equipment wideband air/fuel ratio oxygen sensor designed to monitor exhaust oxygen concentration and optimize engine performance. This pre-catalyst sensor uses advanced sensing technology to precisely measure the air-to-fuel ratio in real time, enabling the engine control unit to maintain optimal combustion for improved fuel economy and reduced emissions.

Key Features:

• Wideband sensing element provides precise air/fuel measurement rather than simple rich/lean switching
• Fast-acting heater reaches operating temperature within seconds for optimal performance
• True direct-fit OE connectors and harness for hassle-free installation
• Threads pre-coated with anti-seize compound right out of the box
• Double laser-welded stainless steel body is fully submersible and sealed against exhaust damage
• 5-wire heated sensor design with 18mm thread diameter and 21.5-inch wire length
• Zirconium sensing element tested to rigorous Bosch quality standards
• 100% functionally tested resulting in seared appearance of protection tube

Bosch invented the automotive oxygen sensor in the late 1960s and remains the world's leading OE supplier. This sensor installs in the oxygen sensor position before the catalytic converter and is engineered to deliver long-lasting, reliable performance.
