HA! made you look! no but really i did do that today all it is a nice pice of dryer hose from home depot that i got for $8 and i only use half of it and some duct tape as well. but yes it can be done the inlet for air on the stock box is a little less than 4" in size, so the 4" hose works well and a ring of duct tape as well, now here are the instructions on how to do it ....
1. remove the tire on the driver side and the wheel well cover
2. you would want to semi-remove (just un-do all the screws) the 1/4 panel and remove the sound damper, and the stock inlet piping.
3. you want to fish the dryer line from inside the panel to the box and making shure you dont cover anywhere the wheel well cover needs to reconect
4. conect the hose to the box this might take a little re-shaping of the hose since it's round the the box as a triangle shape, then seal with duct tape.
5. run the other end to the bummper and fit it somewhere it can pick up air (i have mine pointing to the front to give it a little ram effect (crappy but what can you say for $8)), tape in place
6.put everything back together
and that took me about 3~4 hours with trail and error like trying not to remove the 1/4 panel but the fuse box is in the way..
give her a nice deeper tone at lower levels and noticeable increase in excleration (or that could be because i also replace the o2 senser at the same time) but ya here some pictures of what it looks like and ya i have a k&n in my stock box so eh more power to me!
piping going to the front
piping in the 1/4 panel
that where i have it in the front
that all you see from the engine bay
yup not too flasy, expensive or effective but WELL worth $8 in my oppion or i'm just an idiot
