I finally got around to converting my short ram (sort of) to a short ram ram air (or something like that). Got some defroster hose 7 foot X 2.5" from carquest, a plastic intake adapter, and it barely cleared to my bumper (redline). It's about 41 degrees out and my intake 1 temps held steady in the 40's a little higher at idle but under 60; average while cruising around 46-48.

So...7 degrees above ambient ftw! Plus it sounds badass. Have to see how it holds up on the highway and/or higher temp conditions.

Should reduce my manifold temps as well to some degree.

 

Watch out for that rain.

 

Don't be a hater.

PS...I'm moving to the desert btw.

 

pics please

 

Well...if I get around to it.

Basically I took out the driver's headlight; disassembled my intake, I just attached the intake adapter to my filter (it's an aem type filter with an opening at the top unlike the k&n ones; spectre makes the adapter) then attached the ram air hose to the adapter/inlet with a reducer coupler (3" to 2.5") and clamped it down until it held tight. Then routed the hose through the old intake box to fender well inlet and pulled it through to the front bumper area behind the headlight (just BARELY fits on this side). Then added the filtered velocity stack to the front (it's for a motorcycle I believe) and clamped that down then mounted it to the bumper foam with a drywall screw and zip ties Put everything back together and put the headlight in. Took 7 feet of the hose (the whole thing) to get it done, it would take less on the passenger side.

Don't know if this would work on the cobalt, I'd have to see the space behind the headlight and the space between the bumper and the a/c condensor/he/radiator.
