The PX500 range is designed for twin SU, IDF and DRLF applications where only one filter is required for both carburettors.
The filter is made from Pipercross multi laminate competition foam and supported internally by an expanded metal cage. The filter element and baseplate are ordered separately.

Always use the largest element possible and ensure that there is at least a 19mm gap between the mouth of the trumpet and inner face of the filter.
