Do everyone a favour and hit the caps lock key. Thanks.
Now, check the tutorial section of this very site and scroll to the bottom, type in 'cold air' or 'heat+shield' or something similar and watch the results hit you in the face.
Other option is ebay, there used to be a group or two who sold them... very easy to install, just have to take the pod out and pop the shield in, then put the pipe back in through the shield.
