At the heart of the unique DesignTek air filter is a specially developed polyurethane foam which acts as a filtration medium, higher both higher performance and life expectancy then paper air filters. The PYRAMID VORTEX design outer surface area will absorb larger amounts of airborne dirt particles, while still allowing air to flow freely. High flow with excellent filteration.This Product Fits: Porsche 928 4.5 09/77 - 08/82Porsche 928 4.7 S 09/79 - 07/86Porsche 928 5.0 GT 01/89 - 07/91Porsche 928 5.0 S 09/85 - 05/94Porsche 928 5.0 S4 08/86 - 07/91Porsche 928 5.4 GTS 08/91 - 11/95

BMC air filters are designed and produced to ensure a higher air flow than original paper filters. In F1, for example, BMC cotton filters minimize the loss of air flow pressure passing through the air filter; this way ensures the best conditions for full exploitation of maximum power. Therefore the benefits of replacing the original paper filter with BMC cotton air filter, produced using the same technology and materials as the F1 air filters, are evident.DESIGN AND MATERIALS Qualified engineers using advanced software and expert technicians using the latest technologies produce BMC air filters. An F1 filter must be very light, must be made of the best raw materials and must improve performance. For this reason we use only alloy mesh with epoxy coating to ensure protection from petrol fumes and from oxidization due to the humidity of the air. The filtering material is composed of a special cotton gauze soaked with low-viscosity oil to give you the best air permeability.This Product Fits:Porsche 928Panel Filter Size:- width - 158mm- height - 515mm
