The Chevrolet Performance Sensor Assembly Oil Pressure (part number 12677836) is an OEM-specification electric pressure sending unit engineered for GM LS-series engines. This precision monitoring component features a 16mm x 1.50 male-threaded interface and delivers real-time oil pressure data to the vehicle's gauge or engine management system, ensuring operators maintain continuous visibility into critical engine parameters during high-demand operation.

As a factory Chevrolet Performance component, this sensor meets OEM electrical and mechanical specifications for LS-platform applications. The 16mm x 1.50 thread size and male connector design ensure proper fitment in LS blocks without adapter plates or modifications. The sender unit transmits accurate pressure readings across the full operating range, providing the data resolution required for engine diagnostics and performance tuning. Weighing just 0.06 lbs with compact dimensions of 2.6 x 1.5 x 4.85 inches, the assembly integrates seamlessly into tight engine bay configurations without adding bulk or interference with adjacent components.

This sensor is essential for LS engine builders, performance shops, and vehicle platforms running GM LS powerplants—from street machines and trucks to custom installations requiring factory-grade instrumentation. Whether diagnosing oil pressure anomalies, supporting engine break-in protocols, or maintaining baseline performance data during track sessions, accurate oil pressure sensing is non-negotiable for engine longevity and reliability. Chevrolet Performance parts carry OEM validation, making this sender a trusted choice for builders who require manufacturer-backed component quality.

LS-series engines have become the standard platform across a wide range of vehicles and applications—from factory Chevrolet performance vehicles to complete engine swaps. Sensor assemblies designed for this platform command premium pricing when sourced from factory suppliers, making OEM Chevrolet Performance components a cost-effective solution for builders seeking validated, direct-fit parts without custom fabrication or guesswork.

Part number 12677836 is the exact sender assembly specified for LS applications requiring OEM oil pressure monitoring. Verify fitment with your specific LS engine block and gauge configuration before ordering to ensure compatibility with your instrumentation harness and sender bore threading.
