Thread: Cheap cold air trick

This is a cheap trick & some may not approve of it. Simply run intake tubing or house air ducting from the bottom drivers side bumper & up through the fender well directing the tubing at the CAI. Easier to do if front bumper is taken off. (Will add pics soon)

Yeah, but this works more like Ram Air with the tube pulling in air from the underside of the front bumper. Not a filter shoved into the fender well that has to suck in air through the tiny hole in the abs plastic in the wheel well.

That sort of setup really has no merrit. The reason being barametric pressure differences around the tube opening and that within the fender well. Air simply will not be forced up through that tube or hose at a high enough rate and force. You're right though it is cheap.

NVR really thought about barometric pressure or bends reducing power. I kinda did it for fun & I don't need it anyways. Got real Ram Air though the hood. But if it could really work or at least cool an engine it'd be okay.

Well I agree that fwi aren't the greatest cuz uve got the headlight assembly in the way. But most companies that offer cai kits come with a box that the cone filter sits in. I got my thrasher cai kit for cheap used and I like it. Don't figure it runs much better then a cheapy homemade fwi though. I even took my headlight out when I went to the track. The way the box is setup it looks like it creates a perfect ramair setup. But again,I don't see it workin that great. Besides I still had to go to homedepot to get some pcv tubing for the inlet tube cuz the thrasher kit didn't come with a new one.

I'm wishing cold air intake boxes were sold seperatly for those of us that do buy aftermarket CAI's that don't come with the box. So we don't have to try and build our own out of peices of plastic, metal or cardboard. I have a ram air hood and could realy use that air box. No way I'm spending 239$ on the whole kit though.
