cold air intake box or extension out of bay?

[Awyman18]

so my cold air intake is in the engine bay, and i either want to build a box around it to keep the hot air out of it (if its that effective) or buy a coupling, and some pipe and extend it out of the engine bay?

i actuly started a thread about this earlier in the year heres the link. hope it helps, im still making the molds to get the fit right

basickly you could make a hose going from the stock snorkle hole to the bumper to get freash air,the way i would do it is to remove the pasanger side fog light make a velocity stack and run a pipe up to the snorkle hole which is followed by the box which keeps the hot air out i would make the box that houses the filter element out of fiberglass since it doesent heat up like aluminum does ( race cars use it because there always moving air never standing still like a daily would) if you get aluiminum pipes wrap them in exshaust wrap to keep the pipes cooler

hmmmm that does sound pretty good, hmmm...wat about extending a pipe off the afm, and putting the cold air intake by the bumper?

This is covered in the FAQ's. Box vs 'out of bay'... Stock is better than an open filter in the engine bay though.

what cre said,

wat about extending a pipe off the afm, and putting the cold air intake by the bumper

but i would think that if you put the filter at the bumper rain, debris, speed bumps, sand/mud and alot of other stuff would come into contact whith you filter and that would need constant replacments. unless you fabed a shild of some sort

this is what i initaly thought, correct me if im wrong

There are devices you can install is you're planning on driving through flooded areas (which I advise against no matter where your air filter is located). This too is mentioned in the FAQ thread if I remember correctly... I know I've posted data on it a couple times now.

As for debris and mud and such... The idea for most is KEEP the fog light in place. If you remove the fog light it should be obvious that more frequent servicing/cleaning will be needed on the outward facing portion... remember, the rear should stay relatively clean and free breathing.
