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.

Performance Gain: 8-11hp, 8-10ft-lb
Flow Bench Data: Stock Intake 905 CFM : Eventuri Intake 1025 CFM

Fitment: Porsche 991.1 and 991.2 GT3 RS

The Eventuri 991 GT3 RS intake system consists of a number of components engineered to perform a specific purpose and fabricated to the highest of standards. We use 100% pre-preg carbon fiber with no fibreglass which means we can achieve a smooth internal surface to maintain smoother airflow. Here are the details for each component and the design ethos behind them:

Each intake system consists of:
Carbon Fiber Double Venturi Filter Housing
Bespoke High Flow Dry Cone Filters
Carbon Fiber Inlet Ducts
Silicon Coupler Internally Stepped
Laser Cut Stainless Steel Brackets

The 991 GT3 RS Filter Housing comprises of 2 bespoke high flow filters, aluminium cowls, laser cut brackets and the carbon pod itself. The carbon pod shrouds the reverse mounted filters and smoothly shapes the airflow down to the throttle body. This smooth reduction in cross sectional area invokes the Venturi effect where the airflow accelerates whilst maintaining laminar conditions. It can be thought of as a large velocity stack - below is a diagram to show the comparison between our patented design and a regular intake system. Further details can be read in the Technology page.

BESPOKE CONE FILTER

In order to achieve the highest flow rate possible we designed a filter element to make as much use of the space available in the engine bay as possible. This new filter has an outside diameter of 192mm or 7.6" and when flow tested with a housing using a 4" opening is able to flow up to 900 CFM at 28" H2O. The filter medium is ISO tested to ensure that filtration is in line with OEM standards and is also dry. The filter is constructed with our signature flow cones to aid in the Venturi housing principle.

CARBON DUCTS

The ducts channels ambient air from the side vents to the filter housing. In order to ensure a good seal against engine bay heat - they are secured to the filter housing at 3 points and use a neoprene gasket for an airtight seal . The ducts were designed to have the maximum internal volume possible within the given geometry of the engine bay. This ensures that the filter housing is able to draw with minimum restriction.

SILICON COUPLER

Our silicon coupler replaces the stock flexible tube to the throttle body. It matches the OEM throttle body with an internal step to ensure smooth flow.
