Go to bunnings and buy some straight plummbing pipe, along with a 90' beng pipe and a cap.
When you install a FMIC you will have a hole where the old cooler piping used to go.
Fit the piping up, adjust it to where there is a vent on the front bar, shape the pipe if you want, and then sticky tape it to the back of the front bar.
You can then fibre glass the vent onto the front bar from the inside of the vent, and spray it.
Thats what i did, it looks awesome and really helps.
SOrry its a short explanation, but if you want me to post up some pics of mine I can.
Cheers
