UFI Filters has introduced what it says is a revolutionary in engine air filtration technology, The UFI multitube has a patented tubular structure, which replaces the traditional panel filter offering increased filtration performance and greater engine power in a reduced space.

The UFI Multitube will feature as original equipment on the Porsche GT2RS and will also soon feature on many high-volume applications.

UFI says what makes the filtration technology revolutionary is the particular geometric flexibility of the UFI Multitube cartridge, the structure of which allows for pipes to be positioned in parallel, in series or in different geometries, with different diameter and lengths depending on engine space requirements. This means the new UFI technology offers modularity and a flexible design to suit the specific needs of car manufacturers.The space saving design is particularly advantageous for hybrid cars, where space in the engine compartment is especially limited due to the presence of an electric device in addition to the mechanical systems.

The Multitube also offers better fluid dynamics, ensuring a linear flow in terms of air passage. This reduces resistance and minimises the loss of pressure and energy. This in turn means extra horsepower whilst also minimising harmful emissions and fuel consumption. Tests carried out by an external laboratory on an Audi 1.4 TFSI have confirmed an increase in horsepower of up to 4% with respect to the standard air vent.

UFI says Another revolutionary feature of the new filter involves the specific materials of the media’s deep filter cartridge, which is composed of hydrophobic fibres that retain full functionality throughout the entire life cycle of the product. In contrast, traditional products in pleated cellulose have significantly reduced filtration capacities. This is due to the deformation of materials that, with the inevitable absorption of humidity, causes a loss in air flow pressure, which in turn has a negative impact on engine power.
