Before you go and do that, Take a look. On my 1988 5ktq if you were to "cheese" the cold fender side of the box you'd be doing it on the wrong side of the filter. In fact there would be no filter action at all. Double check your car but from memory I think this is correct. On mine. The lid would be the side to cheese but that is the hot side. But it would be filteres anyway. But hot. Neil
