These are the Pipercross PX300 air filter elements, to be used in combination with the PX300 baseplates.
An explanation of this ingenious system can be found HERE.
The filters are produced from triple-laminated Pipercross filter foam and are supported on the inside by sturdy mesh.
The filters are produced in two basic shapes, the “Dome” and the“Box”.
The differences between the two are best demonstrated in the photos below:

The filters always have the same "groundplan" of 190 x 150 mm in order to fit onto the base plates.
The differences are in the shape and in- and external height.
To allow you engine to breath as freely as possible, we advise you to take the highest filter that you can fit under the bonnet.
If you are using rampipes or trumpets, then please allow at least 19 mm of space between the trumpet mouth and inner face of the filter.
The following heights are available for the various models:

Attention!
This is the filter element only.
To be able to use this, you will always require a PX300 base plate, suitable for your carburetor.
The various baseplates that we have available can be found in the PiperCross PX300 department.
