J.C. Whitney SET-JARBV960908-C OEM Replacement Oxygen Sensor Set

The J.C. Whitney SET-JARBV960908-C is an OEM replacement oxygen sensor set designed to restore proper air-fuel mixture monitoring and engine management performance. As a direct-fit replacement, this O2 sensor set is engineered to match the original equipment specifications of the target vehicle, ensuring seamless installation without modification.

Oxygen sensors — also known as O2 sensors or lambda sensors — play a critical role in your vehicle's emissions and fuel efficiency systems. They continuously monitor the oxygen content in exhaust gases and relay that data to the engine control unit (ECU), which adjusts the fuel injection mixture in real time. A worn or failing oxygen sensor can trigger a check engine light, reduce fuel economy, and increase harmful emissions.

Key Features:

• Direct OEM replacement — no cutting or splicing required
• 4-wire heated sensor design for fast warm-up and accurate readings
• Threaded-in mounting style with M18-1.5 thread size
• 7/8 in. hex size for standard socket installation
• Sold as a set for complete system replacement
• 1-year, unlimited-mileage J.C. Whitney warranty

Replacing a faulty oxygen sensor with a quality OEM-spec unit like this J.C. Whitney set helps maintain optimal combustion efficiency, protects your catalytic converter from damage caused by a rich-running engine, and keeps your vehicle running within factory emissions standards.
