SINOTRUK HOWO Air Filter Sensor – OEM WG1200190040

When your HOWO truck’s air filter becomes clogged, engine performance drops and fuel efficiency suffers. The WG1200190040 air filter sensor (also called intake restriction switch) monitors filter differential pressure and alerts the driver before damage occurs.

We have supplied SINOTRUK HOWO genuine and OEM-quality parts to fleets, workshops, and distributors across Africa, Middle East, Southeast Asia, and South America since 2017. Every WG1200190040 sensor is tested for continuity, thread fitment, and pressure switch accuracy before dispatch.
