4.5" intake opening...?

i ordered a adapter to get rid of the stock air box on my 3k but the adapter is 4.5'' opening, what brand of filters even have a filter with that size opening. its just a circle opening.

I will see if I can get a K&N and let you know.. btw you never got back to me about the HHH dataloger.. how do you like it?

i havent really had a chance to try it out yet, but mine came with a gray box that plugs in with a usb plug, and the box has the serial conector on it, and i tried the program with out the box and it didnt connect so when i get time im gonna try with the box, i might try tommrow. but let me know about the intake its a 4.5 inch opening thats round. thanks man.
