Bosch 15732 Universal Oxygen Sensor 4-Wire Heated O2 Sensor

The Bosch 15732 is a premium universal heated oxygen sensor designed for situations where original vehicle connectors or cables are too damaged to reuse with an exact-fit oxygen sensor. This 4-wire universal O2 sensor provides accurate oxygen level readings to help your engine control unit optimize air-fuel mixture for improved performance and reduced emissions.

Key Features:

• 4-wire heated design with 28.4-inch wire length for maximum harness replacement flexibility
• OE SmartLink connector system requires no soldering for easy installation
• Stainless steel body is fully submersible and sealed tight to protect against exhaust emissions damage
• Fast-acting heating element allows sensor to reach operating temperature within seconds
• Narrow-band sensor with 0-1V voltage range for precise air/fuel ratio monitoring
• Thread-in mounting style with 22mm hex size
• Factory tested to meet Bosch rigorous quality and performance standards

Bosch invented the automotive oxygen sensor in the late 1960s and remains the world's leading supplier of O2 sensors. This universal sensor utilizes a sophisticated zirconium and yttrium oxide sensing element that withstands extreme exhaust temperatures and provides long-lasting, reliable performance. All installation components are included, and wire splicing can be completed without soldering.

Wire Configuration: Black wire (signal), gray wire (ground), and two white wires (heater). Universal sensors are ideal when factory connectors cannot be reused, helping restore proper engine operation, improve fuel economy, and reduce harmful emissions.
