20mm GM Oil Level Sender Plug

The 20mm GM Oil Level Sender Plug by Canton is an essential component for General Motors engine builders and enthusiasts running custom oil pan configurations. This precision-engineered sender plug replaces the factory oil level sender unit, making it ideal for custom sump installations, high-performance builds, and modified engine bays where original pan geometry has been altered. Whether you're upgrading to an aftermarket oil pan for improved ground clearance, installing a dry-sump system, or simply need a direct replacement for a damaged sender, this Canton unit delivers OEM-quality functionality at a competitive price point.

The 20mm sender plug features a standardized GM-compatible thread pattern that interfaces directly with factory oil level sensing circuits, ensuring accurate dashboard gauge readings without recalibration. Canton's engineering focuses on reliable dielectric properties and corrosion resistance—critical factors in engine oil environments where moisture and thermal cycling stress sender connections over time. The compact 7.45 x 0.9 x 8.3-inch form factor and lightweight 0.18 lbs construction minimize packaging constraints in tight engine compartments, while precision machining ensures a leak-free seal when properly torqued to specification.

This sender plug is best suited for LS engine swaps, modern small-block builds, and any project requiring aftermarket oil pan installation on GM platforms. Professional mechanics and weekend warriors alike rely on Canton components for long-term reliability in modified engines where oil temperature and pressure monitoring directly impact engine longevity and safety. Installation requires basic hand tools and careful attention to thread engagement; always verify your specific pan's sender boss diameter and thread pitch before ordering to ensure seamless fitment.
