Replacement REPE960901 4-Wire Oxygen Sensor 15 In. Wire Thread-In Mount O2 Sensor

The Replacement REPE960901 is a direct-fit, thread-in oxygen sensor (O2 sensor) designed as an OEM-style replacement. Featuring a 4-wire heated design and a 15-inch wire length, this sensor installs via a standard threaded mount and restores proper exhaust oxygen monitoring to your vehicle's engine management system.

Key Features:

• 4-Wire Heated Sensor – Reaches operating temperature quickly for fast, accurate readings
• 15-Inch Wire Length – Provides adequate reach for proper routing and connection
• Thread-In Mounting – Direct bolt-in installation using standard oxygen sensor socket
• OEM Replacement Design – Engineered to match original equipment specifications
• Threaded Bung Mount – Fits standard exhaust bung for secure, leak-free installation

The oxygen sensor continuously monitors exhaust oxygen levels and sends voltage signals to the engine control unit (ECU), enabling precise fuel trim adjustments for optimal combustion efficiency, reduced emissions, and better fuel economy. A failed O2 sensor can trigger a Check Engine Light and cause the vehicle to fail emissions testing. This Replacement-brand sensor restores factory-level performance at an economical price point.
