Malossi MHR air filter Honda PCX 125 >2021

Malossi W BOX MHR air filter for Honda PCX 125 Euro 5 / Euro 5+ from 2021 onward.

The filter is the first point of restriction in the intake. Its job is to retain dust and particles without unnecessarily hindering the passage of air. When the original element becomes saturated, the pressure drop increases and it becomes harder for the engine to draw in the flow it needs.

The W BOX uses a synthetic hydrophobic filter media with uniform polyester fibers. Malossi states a permeability of up to 2800 l/s·m² with a pressure drop of only 200 Pa, aiming to maintain good flow without sacrificing filtration capacity.

The filtering surface makes use of the available volume in the box to reduce fluid-dynamic losses in the intake and help the engine breathe with less resistance.

On the PCX 125 it can be fitted without the need to readjust the ECU. Its purpose is not to radically modify the amount of air the engine receives, but to reduce the restriction of the filter element while maintaining the original intake system.

Another advantage is that the filter is washable and reusable. According to Malossi, it can be cleaned with soap and water and recover at least 90 % of its initial performance, avoiding the need to replace the complete element at every maintenance interval.

To maintain good intake flow, we recommend checking and cleaning the filter periodically, especially if the motorcycle is regularly ridden in very dusty areas. A saturated filter increases resistance to airflow and ultimately cancels out the very advantage of fitting an element with higher permeability.

What does it offer compared to a conventional filter?

• Higher permeability: facilitates the passage of air through the filter element.
• Lower pressure drop: reduces the resistance the air encounters before entering the engine.
• Hydrophobic media: the fibers do not absorb water.
• Washable and reusable: it allows maintenance to be carried out and the filter to be used again.
• Specific design: geometry adapted to the PCX 125 airbox.
• No ECU adjustment: it can be used with the original electronic management.
