J.C. Whitney SET-JARBJ960905-A OEM Replacement Oxygen Sensor Set

The J.C. Whitney SET-JARBJ960905-A is a direct-fit OEM replacement oxygen sensor set designed to restore proper fuel management and emissions control to your vehicle. Oxygen sensors — also called O2 sensors or lambda sensors — monitor exhaust gas composition and send real-time feedback to the engine control module (ECM) to maintain an optimal air-fuel ratio. A failing sensor can trigger a check engine light, reduce fuel economy, and increase harmful emissions.

Key Features:

• OEM Replacement Design: Direct-fit construction for straightforward installation without cutting or splicing
• 4-Wire Construction: Heated sensor design for faster warm-up and accurate readings across operating temperatures
• Threaded-In Mounting Style: Secures reliably into the existing bung in the exhaust system
• M18 x 1.5 Thread Size: Standard thread pitch compatible with most domestic and import applications
• 7/8 in. Hex Size: Works with standard O2 sensor sockets for easy removal and installation
• Sold as a Set: Includes multiple sensors to address upstream (before catalytic converter) and downstream (after catalytic converter) positions
• 1-Year Unlimited-Mileage Warranty: Backed by J.C. Whitney's quality guarantee

Replacing worn or failed oxygen sensors helps restore peak engine efficiency, improve fuel economy, and keep your vehicle running within emissions standards. This J.C. Whitney O2 sensor set is built to OEM specifications for a reliable, long-lasting repair.
