Ford Ranger Forum : “Cold Air intake”

PVC pipe, hose clamps, and a filter.

You don't. Go buy one you cheap prick.

But seriously, don't "Make" stuff for your car, unless it's welded headers or something of that nature. I've seen cats replaced with beer cans, resulting in some nasty stenches...

Im surpised you can't find one. Check ebay, youll find one for cheap there. I have rocked multiple Ebay cold air intakes. The only difference is the filter and the brand name. Everything else is just belt steel, hose clamps and rubber connnectors.

Some eBay parts are absolute junk.  Cheap plastic then bends and folds when it's clamped.

They may have cheap parts, but steer clear of eBay only brand parts.  If it is a recognizable name it will probably be ok.

build a housing around the air filter and ram air it...you'll get similar if not better air mixture as if you put a cold air intake on...and it's cheap.  get a chunk of dryer vent tubing and take off the stock cover for your air filter.  run the dryer tube to where your fog lights go and you're set; oh, helpful tip, make a new tube for your mass air sensor that does a 90 going toward the front of your truck...this way the engine will pull more air (because it thinks it is getting less)
