can someone tell me how to find an amsoil air filter with a 5 inch flange/opening and around 10 inches long. it was crushed in a previous wreck and it seems to work good for the truck so i would like to stick with it, but there website filters only go from 4.5 to 6 inch i think its just a drop in filter no heat shield or box or anything ,and only connects to turbo through a plastic flex tube ,and would another type of filter work if i cant find this one..2001 24valve

 

Google K&N you can get the size & shape you need I put a huge cone shaped one on mine & used a 4 in pvc cap (modified) to couple it to the stock inlet hose
