Product Overview
Pipercross PX300 D-Shaped Competition Air Filter C3004 – 190mm x 115mm
The Pipercross C3004 is one of the taller filters in the PX300 range, a family of D-shaped foam filters built for carburettor engines. Every PX300 filter shares the same 190mm by 190mm footprint (measured across the tabs); only the height changes. The C3004 stands 115mm tall outside and gives 100mm of usable internal height, so it suits installations where the trumpets or carb inlets sit fairly high above the base plate.
Construction and filtration
Instead of paper, Pipercross uses layered polyurethane foam of differing densities. Coarser foam catches the larger particles while the denser layers trap fine dust, and the open structure keeps flow high. The element is washable and reusable: clean it, re-apply the dirt-retention treatment, and it is ready for another season of road or track use.

Choosing the right height
Pipercross recommend leaving at least 20mm between the end of the trumpet or carb inlet and the inside face of the filter. Measure from the base plate to the top of your tallest trumpet, add 20mm, and check that the result is no more than 100mm for this filter. Where space allows, the tallest filter that fits will give the most airflow, so compare the C3004 against the other PX300 heights before ordering.
What you need to fit it
This listing is for the filter element only. A PX300 base plate matched to your carburettor (for example Weber DCOE, Dellorto DHLA, Solex or SU patterns) is sold separately, as are Pipercross cleaning kits. Fitting is straightforward once the correct base plate is in place: the filter locates over the plate and is secured using the base plate’s fixings. Check bonnet clearance with the engine rocking on its mounts before your first drive, and inspect the foam regularly if the car is used on dusty circuits or loose surfaces.
