Bosch 0 258 030 142 Heated Oxygen Sensor - 0 258 030 142 4-Wire

The Bosch 0 258 030 142 is a premium heated oxygen sensor (lambda sensor) designed to provide precise air-fuel ratio measurements for optimal engine performance and emissions control. As the inventor of the automotive oxygen sensor in 1976, Bosch continues to lead the industry with advanced sensor technology and proven reliability.

Key Features:

• 4-wire heated design for faster response and accurate readings
• 703mm (27.7 inch) overall length for proper fitment
• Zirconia ceramic sensing element for precise oxygen measurement
• Vehicle-specific connector for direct plug-and-play installation
• Supports efficient combustion across all engine types including diesel
• Helps maintain proper catalytic converter operation and reduce emissions
• Post-catalytic converter placement (cylinders 1-3)

Bosch oxygen sensors utilize advanced zirconia Nernst cell technology to measure oxygen content in exhaust gases with exceptional accuracy. The sensor provides real-time data to the engine control unit (ECU), enabling precise fuel adjustments for stable combustion, improved fuel economy, and reduced harmful emissions. This genuine Bosch sensor meets or exceeds OEM specifications for quality, performance, and durability.
