## Overview

The OTC 6500 Flexi-Head O2 Sensor Wrench features a pivoting flexible head designed specifically for removing stubborn 7/8" oxygen sensors. Compatible with 3/8" drive extensions and wrenches, it offers superior access and torque in tight engine spaces. Its slim, durable metal build ensures precision and longevity, making it an essential tool for professional mechanics and DIY enthusiasts alike.

## Description

This sensor wrench has a flexible head design that assists in the removal of stubborn O2 sensors that is 7/8 inch in diameter, a common size to most vehicles. Features allow extensions or wrenches to apply force in tight areas, even on seized components. Pivots to allow more angles of placement.

Review: Excellent tool - Great tool. Worth the $. This was the only tool I could find that could remove the 4 O2 sensors in a 2012 Ford Mustang V6.
Review: Flat Rate Must Have F**** ho2s sockets - Superior to most HO2S wrenches, sockets, etc. it’s slim and extremely useful in tight spots. The head is very tight and you have no slop. The bottom is equipped with a 3/8 drive for extensions and you can get as much torque out of it as you need. I borrowed this once upon a time from a fellow technician to get a sensor out due to its poor location this was the only tool to get to it without removing components all for a couple ticks(if you know you know).
