Bosch 13868 Oxygen Sensor Heated 4-Wire Post-Cat

The Bosch 13868 Super Class Oxygen Sensor delivers precise emission control for your vehicle's engine management system. This downstream oxygen sensor is designed to mount after the catalytic converter, monitoring exhaust gases to ensure optimal engine performance and fuel efficiency.

Key Features:

• Premium ceramic technology incorporating Zirconium or Titania and Yttrium for superior protection against mechanical and thermal shock
• Patented catalytically activated fine particle filter prevents contamination for extended sensor life and ensures precise voltage readings to the engine's emission control computer
• Dual-filter design provides double protection against exhaust gas contamination
• 4-wire heated design with 25.6-inch wire length for quick operation and accurate readings
• OE-style silicone boots ensure proper fit, function, and appearance
• Direct plug-in installation with no cutting or splicing required
• Helps prevent premature catalytic converter failure by maintaining proper air-fuel ratios

This Bosch oxygen sensor is rigorously tested to deliver perfect performance while maximizing fuel economy. The heated design allows the sensor to reach operating temperature quickly, providing faster closed-loop operation for reduced emissions and improved drivability.
