Bosch 13952 Oxygen Sensor Heated Sensor - 4-Wire O2

The Bosch 13952 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 Bosch's Super Class technology, this sensor features advanced filtration systems that protect against contamination and ensure long-lasting, accurate operation.

Key Features:

• Premium ceramic construction with Zirconium or Titania and Yttrium elements for superior protection against mechanical and thermal shock
• Patented catalytically activated fine particle filter prevents contamination and ensures precise voltage signals to the engine's emission control computer
• Dual-filter design provides double protection against exhaust gas contamination for extended sensor life
• 4-wire heated design allows rapid sensor activation for accurate readings even during cold starts
• 28-inch wire length provides flexible installation options
• OE-style silicone boots ensure proper fit, function, and professional appearance
• Direct plug-in installation with no cutting or splicing required

This oxygen sensor helps prevent premature catalytic converter failure by maintaining optimal air-fuel ratios, reducing harmful emissions while improving fuel economy. Rigorously tested to meet or exceed OE specifications, the Bosch 13952 is designed for installation before the catalytic converter. Sold individually as a direct OE replacement.
