Your best bet would be to go to Autozone or your local parts house and look for the Spectre intake tube for the Honda Civic
Comes in a generic looking plastic case it'* around 35 bucks.
Here'* a link for the tube you need spectre intake tube
The next thing aould be the filter. www.ajusa.com
for the K&N RX-4750.
Quite a few of us have this filter and it would probably be the best one for ya
Coupler to the throttle body can be found here http://www.siliconeintakes.com/reducer.htm
You'll need the 3.75" to 3" reducer.
The best place for the IAT sensor is in the filter. You can either get the IAT harness from www.intense-racing.com
. It'* this one..Casper'* Electronics IAT Harness Extender. Or,if you are handy with a soldering gun,just extend the IAT wires to reach the hole in the filte . Which happens to be the best location for it.
Fab up a heat shield and you're good to go
