for sale Custom DCI Green Filter Intake, the filters are green filter USA 6" dual inverted cone and 3" intakes; i mated with 2.25"-2.5 couplers and used a silicone coupler to mate.
i made them because to provide more air and less restriction than any other DCI out there. and green filter usa use a way better cotton. you can research their filters for reference. these are 65 dollars filters, each. just looking to clear space, had them for 5 to 6k miles.
see installed pic: i included the BMS cone for reference. you can see the size difference and gives your engine bay a nice contrast.
