just wondering if anyone knows if installing a whipple supercharger on an 03 cobra will cause a visual smog check failure in california? I have a 2000 f150 that is completely stock but had a section cut out of the stock plastic airbox and they failed me on the visual, of course this was the last portion of the smog test they did so they could still charge me $60 for a failed smog check.
