Pipercross Plus BMW M3/M4 Drop In Panel Air Filters (G80/G81/G82/G83)

Pipercross Plus air filters have 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. 

These Pipercross air filters are exceptional for the money. We use the PLUS filters on our Stage 1 & Stage 2 G80/G82 engine tuning packages as they offer excellent flow and negate the need for a full intake kit.

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 breathability 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.
