Designed for use in demanding engine compartment environments, the raw air box provides the flow-optimized connection between outside air and the air filter. The dip-molded part – the raw air box – is mounted directly onto the air filter, forming a secure, sealed unit. The integrated bellow closes flush with the bonnet at the top, ensuring that no damage occurs when opening and closing the bonnet while simultaneously providing an optimal seal. This ensures that only outside air is drawn in, which then flows in a controlled manner through the filter and reaches the engine cleanly.
As a raw air box with bellows, the component performs an important function within the air intake system: it reliably separates the unfiltered outside air zone from the filtered clean air side, reduces mechanical stress caused by relative movements between the bonnet and the filter housing, and thus makes a significant contribution to the longevity of the overall system. The soft-elastic properties of the bellows dampen vibrations, reduce noise emissions and at the same time allow the bonnet to rest directly on the bellows – without damage and without any loss of sealing integrity.
Our raw air box with bellows therefore delivers clear added value for vehicle manufacturers, developers and service personnel. It simplifies installation, enhances operational safety and enables a stable, clean air supply – day after day, even under challenging environmental conditions. Wherever air needs to be safely guided and filtered while simultaneously requiring flexible, compensation-capable connections, this dip-molded part is the right choice – in vehicle manufacturing and engine technology, as well as in numerous other industries and applications.
