siong .. firstly u must know ...
CAI is just a hose. (in this case)
one end of the hose, face oncoming air in front of your car (or anywhere else u can think) .. the other end, facing your OpenPod airfilter, or fit into your stock airfilter boz/rampipe...
its just to draw cool air from outside... its that simple.
there r many ways to put the hose ,, jack up your car, dont be lazy n be creative ... its very very simple... good luck!
