Ok so heres my deal i bout this truck (01 f350 7.3 PSD) it has an air aid air filter kit. Its in desperate need of a new filter the one on it is pretty tore up but i dont want to spend $100 bucks on an air filter. Anybody got any ideas on what other filter will fit? It clamps on a 6 inch tube and probably 10"-12" long offset oval. It sits in a box pretty close to the battery so i think it still needs to be oval cone shaped.
