J.C. Whitney SET-JRV96090004-2 OEM Replacement Oxygen Sensor Set

The J.C. Whitney SET-JRV96090004-2 is an OEM replacement oxygen sensor set designed to restore proper exhaust gas monitoring and fuel management to your vehicle. Oxygen sensors play a critical role in your engine's performance by measuring the oxygen content in the exhaust stream and sending real-time feedback to the engine control unit (ECU), allowing it to maintain the optimal air-to-fuel ratio.

A failing or degraded oxygen sensor can trigger a check engine light (CEL), reduce fuel economy, increase harmful emissions, and cause rough idling or hesitation. Replacing worn sensors with a quality OEM-style unit like this set helps restore factory performance and emissions compliance.

Key Features:

• OEM replacement design for direct-fit installation
• Helps restore optimal air-to-fuel ratio and engine efficiency
• Reduces harmful exhaust emissions and supports emissions compliance
• Compatible with upstream (pre-cat) and/or downstream (post-cat) sensor positions depending on application
• Designed to meet or exceed original equipment specifications
• Sold as a set for comprehensive sensor replacement

This oxygen sensor set from J.C. Whitney is a reliable choice for restoring factory-level exhaust monitoring and protecting long-term engine health.
