Ramair oversize Foam Filter 90mm (3.5inch)

These filters have an aluminium ram-pipe neck and a cone-shaped filter element. The cone shape helps guide all the incoming air smoothly into the inlet manifold, which reduces unwanted turbulence. The filters are cone-shaped to make them easier to fit in tight engine compartments, and the large amount of foam surface area also helps give your engine more power.

The filter is specially reinforced with a stainless steel internal mesh, which we have designed and used in European and world touring cars.


With its big size, advanced technology, and a bell mouth alloy spun base, this filter kit can handle very high levels of power and airflow.
