- Superior Performance: Bosch oxygen sensors draw on decades of design and manufacturing experience since the late 1960s to deliver long-lasting, reliable operation. - Factory Tested: Each sensor meets Bosch quality standards and undergoes a full functional test before shipment to ensure operation within design specifications. - Stainless Steel Body: The stainless steel body is fully submersible and sealed to protect against exhaust emissions and environmental exposure, helping extend sensor life. - Fast Acting Heater: The fast-acting heater reduces warm-up time on Planar and 3-, 4-, and 5-wire Thimble-type sensors, bringing the sensor to operating temperature in seconds for optimal performance. - Ready to Install: Direct-fit OE-type connectors and harnesses, with gaskets or crush washers as necessary for installation, make setup simple and hassle-free. - Applications and use scenarios: - Direct-fit replacement in vehicles using Planar or Thimble-type sensors (3-, 4-, or 5-wire) for reliable, quick restoration of performance. - Replacement in Bosch-equipped engines where fast warm-up and durable stainless steel construction improve longevity in harsh exhaust environments. - Service in emission-controlled exhaust systems where OEM-grade connectors and seals ensure proper fit and leak-free installation.
