J.C. Whitney SET-ARBP960912-B OEM Replacement Oxygen Sensor Set

The J.C. Whitney SET-ARBP960912-B is a direct-fit OEM replacement oxygen sensor set designed to restore proper air-fuel ratio monitoring and engine management performance. This set delivers a plug-and-play replacement experience, engineered to meet or exceed original equipment specifications.

Oxygen sensors — also called O2 sensors or lambda sensors — are critical components in your vehicle's emissions and fuel delivery system. A failing sensor can trigger check engine lights, reduce fuel efficiency, and cause rough running. Replacing with a quality OEM-style unit like this J.C. Whitney set restores accurate exhaust gas readings and helps the engine control module (ECM) optimize combustion.

Key Features:

• OEM replacement design for direct fit and function
• 4-wire construction for accurate and stable signal output
• Threaded-in mounting style with M18-1.5 thread size
• 7/8 in. hex size for standard installation tooling
• Male connector for OEM-style plug-in fitment
• Backed by J.C. Whitney's 1-year, unlimited-mileage warranty

This set includes multiple sensors to cover both upstream (before catalytic converter) and downstream (after catalytic converter) positions as required for the application. Always verify sensor count and position compatibility using your vehicle's year, make, model, and engine specifications.
