ZPAA2960 Air Filter Element is a high-capacity dual-stage intake filter for Dongfeng DCi375-30 diesel engine air intake system. It adopts high-performance composite filter paper to trap dust, sand and road grit in incoming air, delivering purified air for combustion. This aftermarket replacement filter solves insufficient air intake, black smoke under heavy load and premature abrasion of cylinder liner, piston and turbocharger caused by filter clogging, medium rupture and seal leakage. Reliable air filtration maintains proper air-fuel ratio and reduces engine wear for Dongfeng heavy trucks operating on dusty construction sites and long-distance highway freight routes.

Product Advantages High dust holding filter media with low airflow resistance extends maintenance cycle. Optimized internal support structure prevents filter deformation under suction pressure. Integrated PU sealing ring blocks bypass of unfiltered dirty air. Every air filter is inspected for permeability and sealing performance before shipment, OEM profile supports easy installation during routine service.

Applicable Models Fit for Dongfeng heavy-duty commercial trucks equipped with DCi375-30 diesel engine, widely used for heavy-load transportation and cross-region long hauling.
