J.C. Whitney SET-JARBD960902-B OEM Replacement Oxygen Sensor Set

The J.C. Whitney SET-JARBD960902-B is an OEM-replacement oxygen sensor set engineered to restore proper exhaust monitoring and fuel management to your vehicle. Oxygen sensors (O2 sensors) play a critical role in your engine's emissions control and fuel efficiency by continuously measuring the oxygen content of exhaust gases and relaying that data to the engine control module (ECM).

Key Features:

• Set includes multiple sensors — provides complete upstream and/or downstream coverage as required by application
• 4-wire heated design — reaches operating temperature quickly for accurate readings, even on cold starts
• Threaded-in mounting style with M18-1.5 thread size for a direct, secure fit
• 7/8 in. hex size for easy installation with standard O2 sensor sockets
• OEM replacement quality — designed to meet or exceed original equipment specifications for fit, form, and function
• Manufactured by J.C. Whitney, backed by their 1-year, unlimited-mileage warranty

A failed or degraded oxygen sensor can trigger a check engine light, reduce fuel economy, and increase harmful emissions. Replacing worn O2 sensors with a direct-fit set like the SET-JARBD960902-B helps restore optimal engine performance, emissions compliance, and fuel efficiency.
