J.C. Whitney SET-JA960906-D OEM Replacement Oxygen Sensor Set

The J.C. Whitney SET-JA960906-D is an OEM replacement oxygen sensor set designed to restore proper air-fuel mixture monitoring and engine management to your vehicle. Oxygen sensors, also known as O2 sensors, are critical components in your vehicle's exhaust and emissions system — they relay real-time exhaust gas data to the engine control module (ECM) to optimize combustion efficiency, fuel economy, and emissions output.

Key Features:

• Direct-fit OEM replacement oxygen sensor set for a hassle-free installation
• 4-wire heated sensor design for fast warm-up and accurate readings across operating temperatures
• Threaded-in mounting style with standard M18-1.5 thread size and 7/8 in. hex size for compatibility with common exhaust bungs
• Restores proper upstream (pre-catalytic converter) and/or downstream (post-catalytic converter) O2 sensing
• Helps eliminate check engine lights caused by oxygen sensor failure codes (P0130–P0167 range)
• Backed by J.C. Whitney's 1-year, unlimited-mileage warranty

Replacing a faulty O2 sensor can improve fuel economy, reduce harmful emissions, and prevent long-term damage to your catalytic converter. This J.C. Whitney set is engineered to meet or exceed OEM specifications, making it a reliable and cost-effective solution for restoring your vehicle's performance.
