i have a 92 d350 and the guy i got it from tried to make his own cold air but id didnt work. he jest left the filter laying loose on the finder well and it ruined the k&n filter he put on there. he threw away the original air filter box so i couldnt put that bak on it for now so what i did was pulled the original tubing off and just put a cone filter directly on the turbo. the prolem i ran into with that tho was it barely fits and i have to pull the cable off of the altanator and smash the filter on there because orileys does not have any 45 or 90 degree elbows in a 4 inch to put on there and i cant find a cold air intake kit for it through k&n. does anyone know where to get the elbows or the whole kit and which way should i go with it
