[_JET_]

Im looking for a little help. I was installing my new headlights into my car and i was checking out the filter box that is under my headlight and goes into my fender. The box that holds the filter itself was apart and i could actually stick my finger in and touch the filter. I assume this is not a good thing considering that there is air passing through the opening and not through the filter. I was wondering if anyone has done the stealth CAI and if they have any tips for doing this. I assume you just pull all of the useless plastic out after MAF tube and slap a cone filter on? I would get an intake but this seems like the most cost effective way to do this for me. If anyone knows what size filter slips onto the tube as well that would help otherwise i will just measure then get the filter. Oh ans PS i have an 07 2.0 duratec
Thanks
