Pipercross plus has improved strength and rigidity, swapping out the mesh used in the regular Pipercross panel filters and replacing it with a stronger and better looking 1mm steel frame. You can really feel the difference that this change makes to the strength of the filter, even when pulling 100’s of CFM (cubic feet per minute) through the foam.

The Pipercross Plus filter utilises two foams, the 20 PPI Foam and 60 PPI Foam. The 20 PPI Foam is a free-flowing foam that captures the large dirt particles in an optimised thickness of 20mm, this first layer provides a great balance between filtration and flow. The 60 PPI Foam is a 5mm layer that is used to filter out any finer particles that make their way through the more open foam, this layer is mostly for protection, by keeping its thickness to a minimum it doesn’t disrupt the great flow of air this filter allows.

A new stronger frame has been created with breath ability in mind, when compared to our regular mesh, this frame has a 22.1% increase in effective flow area. Not only is this good in terms of performance, but the increased rigidity in the frame will also improve durability. inc. VAT

Presenting an intake which truly sets a benchmark for the BMW G8X M3/M4 platform. Eventuri have carried out intensive R&D to develop an intake which not only improves on the stock M3/M4 but also is future proof in its capacity to cater for high powered builds well in excess of 1000hp. Their system is a complete redesign from the airboxes to the turbo inlets with the aim of reducing pressure loss while increasing the flow rate and keeping inlet temperatures low. They have maximised the usage of the available space to employ 2 custom made filters with a 40% larger filtration area than stock. These are used in Patented Venturi housings to smoothly funnel the air to the turbo inlets. The inlets themselves are up to 160% larger in cross sectional area than stock and are designed with an advanced dimpled inner surface to reduce frictional losses between the flow and the wall boundary. By allowing a “cushion” of air at the wall surface, airflow is able to move through the inlets at higher flow rates with reduced pressure loss. This allows the turbos to draw air with less resistance and therefore reduce the wastegate duty cycle resulting in higher overall performance.

The Eventuri Difference

The G8X M3/M4 Eventuri system uses Patented Carbon Fibre Housings with Eventuri's Gen 2 bespoke filters, which provide an aerodynamically efficient airflow path from the filter to the turbos. Not just another cone filter with a heat shield but a unique design which invokes the Venturi effect and maintains laminar flow conditions to reduce the drag on the turbo
