Bosch 13782 Oxygen Sensor Heated Sensor - 4-Wire O2

The Bosch 13782 S500 Oxygen Sensor is a premium 4-wire heated oxygen sensor engineered to deliver precise air-fuel ratio monitoring for optimal engine performance and emissions control. Built with advanced ceramic technology incorporating Zirconium or Titania and Yttrium, this sensor provides superior protection against mechanical and thermal shock for reliable long-term operation.

Key Features:

• 4-wire heated design for faster sensor activation and accurate readings in all driving conditions
• Patented catalytically activated fine particle filter prevents contamination and ensures precise voltage signals to the engine control computer
• Dual-filter protection system guards against exhaust gas contamination for extended sensor life
• Premium ceramic construction with Zirconium or Titania and Yttrium for exceptional thermal and mechanical durability
• 12.8-inch wire length with OE-style silicone boots for proper fit and function
• Direct plug-in installation with no cutting or splicing required
• Helps prevent premature catalytic converter failure by maintaining optimal air-fuel ratios
• Rigorously tested to ensure performance and fuel efficiency

This oxygen sensor mounts on the passenger side before the catalytic converter and is designed as a direct OE replacement. The heated element allows the sensor to reach operating temperature quickly, ensuring accurate readings from cold starts. Bosch oxygen sensors are known for their precision manufacturing and reliability, making them a trusted choice for maintaining proper engine performance and meeting emissions standards.
