O2 Sensor Socket Tool Set
Professional 5-Piece O2 Sensor Socket & Thread Repair Tool Set
All-in-one kit engineered for efficient, damage-free removal, installation, and thread restoration of automotive oxygen sensors.
Side Slotted Wire Gate Structure
This design features a specialized side-opening slot allowing you to easily slip the socket over the sensor housing without having to cut, disconnect, or damage the vital wiring harness. Safe passage of the wires ensures the sensor stays fully intact during assembly or disassembly.
Offset Sockets for Narrow Clearances
The offset design re-angles the socket drive path, allowing easy access inside deep recesses, low-clearance areas under engine bays, or around complex exhaust manifolds where straight socket profiles cannot reach. This provides high mechanical leverage even in tight spaces.
M12 & M18 Thread Chaser Tools
Ensure smooth reinstalls and prevent cross-threading with the integrated M12 x 1.25mm and M18 x 1.5mm thread chasers. Highly optimized for clearing away baked-on carbon buildup, engine rust, and debris from mounting threads before screwing in new sensors.

Frequently Asked Questions
🔧 How does the side-slotted design protect O2 sensor wires?
The long socket features a 0.31" (8mm) wide side-opening slot, and the two offset sockets have direct wire cutouts. This allows the pigtail wiring connector and harness to feed safely out of the side of the socket body while you loosen or tighten the hex portion, avoiding wire twisting and stripping.
🔧 What tools do I need to drive these sockets and thread chasers?
The tool set utilizes standard square socket drives. You will need a standard 3/8-inch drive ratchet or breaker bar for the small offset socket, the long straight socket, and both thread chasers. For the large offset socket, you will need a 1/2-inch drive ratchet or breaker bar.
🔧 What are the specific thread sizes of the included thread repair tools?
The kit comes with one M12 x 1.25mm thread chaser and one M18 x 1.5mm thread chaser. These are the most common automotive thread sizes used for oxygen sensors, allowing you to clean rust and baked-on carbon buildup out of the exhaust pipe threads easily.
