Why foam? Because, compared to paper or other filter technologies, reticulated polyester foam achieves optimum performance against three key criteria:

the capability to arrest a high proportion of airborne dust while feeding the engine clean air.
the capability to absorb a large amount of dust without reducing air flow capacity.
