This filter is designed to be inserted into a flexible hose such as a rubber or silicone intake pipe. These filters have an aluminum ram-pipe neck and a cone shaped filter element. This integral cone channels all the incoming air towards the inlet manifold, and in doing so reduces unnecessary turbulence. The filter is specially strengthened using a stainless-steel internal mesh, which we have developed & used in European and world touring cars! With its large size, technologically advanced filter and bell mouth alloy spun base this filter kit is capable of handling extremely large power & flow rates.
