Question about air filter
 

what's up guys, i have a comptech cold air intake and i need to find a filter to fit the intake. the one on it is a foam filter so im going to clean this one up but i eventually want to get another one. the size of the mouth on the filter is 4 1/8 inches. does anyone know of a filter that will fit this? i dont think k&n makes one. if i can't find one i might try to force a 4 inch on it...any thoughts?
