J.C. Whitney SET-JC960915-C OEM Replacement Oxygen Sensor Set

The J.C. Whitney SET-JC960915-C is an OEM replacement oxygen sensor set designed to restore proper engine management and fuel system performance. Oxygen sensors — also commonly referred to as O2 sensors or lambda sensors — monitor exhaust gas composition and relay data to the engine control module (ECM), enabling precise fuel trim adjustments for optimal combustion efficiency and reduced emissions.

This J.C. Whitney sensor set is engineered to meet or exceed original equipment specifications, providing a direct-fit installation experience with no cutting or splicing required. Built with quality materials for long-term durability, it is a reliable alternative to dealer-priced OEM parts.

Key Features:

• OEM-replacement oxygen sensor set — replaces worn or failed upstream/downstream O2 sensors
• Direct-fit design for straightforward installation
• 4-wire sensor construction for compatibility with fuel-injected, naturally aspirated gasoline engines
• Threaded-in mounting style with standard hex size for use with common O2 sensor sockets
• Helps restore proper air/fuel ratio, fuel economy, and emissions compliance
• Backed by J.C. Whitney's limited warranty

Replacing a faulty oxygen sensor promptly can prevent catalytic converter damage, improve fuel efficiency, and eliminate check engine light codes related to O2 sensor performance. The SET-JC960915-C is sold as a set for a complete service repair.
