Genuine Engine Air Filter Element 1500A399

The original Mitsubishi 1500A399 Air Cleaner Element is a premium factory-grade intake replacement part explicitly co-developed to guarantee smooth combustion performance in responsive compact powertrains. Utilizing an advanced multi-density porous fiber web matrix, this element secures up to 99% macro-contaminant capture efficiency, preventing fine debris from striking sensitive throttle body components or disrupting mass airflow (MAF) sensors. It incorporates a thick, flexible orange injection-molded compression seal ring that sits flush inside the factory air box container, eliminating common aftermarket risks like perimeter framework buckling or raw, dirty air bypass during heavy acceleration. Routinely replacing your engine air filter every 10,000 to 15,000 kilometers protects internal cylinder liners from premature scoring, eliminates rough vehicle idling, and helps maintain peak fuel efficiency. 

This specific compact rectangular panel design is highly versatile and serves as the primary standard factory air filter footprint configuration for 1.0L, 1.2L, 1.3L, and 1.5L 3-Cylinder and 4-Cylinder global engine architectures shared across multiple manufacturer lines. It offers a direct drop-in fit for the following popular model platforms: [1, 2]
