3330141A – PAI Cummins Boost Pressure Temperature Sensor

Description PAI 050660 is an intake manifold boost pressure/temperature sensor engineered as a direct replacement for Cummins engines using OEM references 3330141 and 4921493. It measures charge-air pressure and temperature in the intake manifold, supplying accurate data to the engine control module for correct fueling, turbocharger control, and overall engine performance. Typical applications include Cummins L10, M11, ISM, and QSM11 engines, including QSM11 marine platforms where an intake manifold boost sensor is specified. The sensor features a robust brass body, standard 9/16-18 threaded mounting, and an oval 3-pin female electrical connector for straightforward installation in place of the original unit. Designed and manufactured by PAI Industries, it offers a high-quality alternative to the Cummins-branded sensor while maintaining compatibility with the original harness and manifold port. • Manufacturer: PAI Industries (reference 050660) • Cross-referenced to Cummins 3330141 and 4921493 • Function: intake manifold boost pressure/temperature (MAP) sensor • Connector: 3-pin female, oval configuration • Thread size: 9/16-18 • Housing finish: brass/yellow for corrosion resistance • Applications: Cummins L10, M11, ISM, and QSM11 engines, including select marine variants
