Lambda Probe Socket 22mm – Professional Oxygen Sensor Tool

Brief Overview

This is a purpose-built deep socket designed specifically for oxygen (lambda) sensor removal and installation in tight engine compartments. The 22mm 6-point hex bore accommodates standard oxygen sensor hex heads across VAG, BMW, Mercedes, Ford, and Opel platforms. Unlike standard sockets, the extended depth and integrated wire clearance design eliminate the need for multiple tools or improvised workarounds when accessing sensors in confined spaces—a common pain point in modern engine bay service.

Key Features

• 6-Point Hex Internal Bore: Precise fit for 22mm oxygen sensor hex heads; reduces rounding risk compared to 12-point designs
• Extended Deep Socket Design: Reaches sensors mounted deep in exhaust manifold bosses without requiring extension bars
• Integrated Wire Clearance Slot: Longitudinal slot cut through socket body allows sensor electrical connector to pass through without removal, saving time on reinstallation
• U-Shaped Notch at Socket End: Provides additional wire routing clearance for congested harness situations
• Opposing Notches Near Hex Opening: Allow tool manipulation in severely restricted access points
• Black-Oxide Finish: Corrosion-resistant coating suitable for repeated exposure to heat and engine bay contaminants
• Coated Steel Construction: Durable, cost-effective material with sufficient strength for sensor service without fear of deformation

Business Advantages for Resellers

High Margin Service Tool: Oxygen sensor replacement is a recurring maintenance procedure across all modern platforms listed. This socket eliminates the need for mechanics to improvise or order custom solutions, creating a reliable SKU for your shop inventory.

Platform Coverage: Single tool covers VAG, BMW, Mercedes, Ford, and Opel—representing a significant portion of European and international shop workload. Reduces SKU proliferation while maintaining compatibility.

Technician Time Saver: Reduces per-job labor time by 10–15 minutes per sensor (no fumbling with extensions, no harness disconnection). This translates to higher job throughput and customer satisfaction, driving repeat orders.

Competitive Differentiation: Many shops lack this specialized tool and resort to standard sockets with extensions or risky improvisation. Offering it as a recommendation positions your shop as equipped and professional.
