Bosch 15088 Oxygen Sensor Heated Universal Sensor - 4-Wire O2

The Bosch 15088 Oxygen Sensor delivers OE-quality precision for reliable engine performance and emissions control. This heated 4-wire oxygen sensor is designed to monitor exhaust gas oxygen levels and send accurate voltage signals to your vehicle's engine control computer, optimizing fuel economy and reducing harmful emissions.

Key Features:

• Premium ceramic technology constructed with Zirconium or Titania and Yttrium for superior protection against mechanical and thermal shock
• Patented catalytically activated fine particle filter prevents contamination and ensures extended sensor life
• Dual-filter design provides double protection against exhaust gas contamination
• 31.9-inch wire length with 4-wire heated design for faster warmup and accurate readings
• OE-style silicone boots ensure proper fit, function, and appearance
• Direct plug-in installation with no cutting or splicing required
• Rigorously tested for optimal performance and fuel efficiency

This oxygen sensor helps prevent premature catalytic converter failure by maintaining precise air-fuel ratios. The heated design allows the sensor to reach operating temperature quickly, providing accurate readings even during cold starts. Designed for driver side installation before the catalytic converter.
