5-Piece Oxygen Sensor Socket Set for Automotive Emission System Service

This 5-piece oxygen sensor socket set is engineered for efficient removal and installation of automotive oxygen sensors used in emission-control systems. Manufactured from chrome-molybdenum steel, the sockets deliver high toughness, resistance to deformation, and long-term wear stability during repetitive torque applications. The set includes a combination of large- and small-mouth sleeves in both octagonal and four-flat geometries to support secure interface with sensors installed in restricted engine-bay spaces.

Finished in a silver-and-black corrosion-resistant coating, each component is sized for versatility across passenger vehicles, motorcycles, and general automotive service environments. Suitable for both professional technicians and DIY users, the compact arrangement allows rapid access to critical emissions components without risk of rounding or fastener damage.
