Coldest possible air into the engine thread.

Ok, ive done search after search on how to get the coldest air into my engine.
Ive got my 3A racing filter in my airbox with an extra 3" hole. Im in the process of getting the 3" mandrel bent pipe, and then ill be working on removing the aixbox all together and making a sheild to reject all the heat. ive got a few questions though...
1) I found this thread on the fordmods website- http://www.fordmods.com/forums/fiendishly-simple-air-pressures-over-an-ef-fairmont-hood-t72008.html- but im struggling to take it all in and come to a final conclusion! What does one make of that?
2) That thread lead me to finding one of these on eBay- http://cgi.ebay.com.au/COLD-AIR-INTAKE-MANIFOLD-INSULATOR-FOR-FORD-EF-BF-6_W0QQitemZ250327134922QQcmdZViewItemQQptZAU_Car_Parts_Accessories?hash=item250327134922&_trksid=p3911.c0.m14&_trkparms=66%3A2%7C65%3A1%7C39%3A1%7C240%3A1318- load of BS or worth it?
3) EF XR6 bonnet vents- How can i capitalize on the fact that theres 2 big f. off holes in my bonnet? the one on the right is located right above the airbox. If i cut a big hole in the TOP of the airbox, and i gunna get more COOLER in there?
Thanks for any help at all!
