Cowl Intake with Windstar air box

I got the idea from a guy on Pirate, I decided to use the entire box, he shortened the non filter holding portion of the box.



















I trimmed the factory vacuum fittings, and plugged them with wire nuts, then painted them black

How has this changed the performance at all? Or what are the benefits?

For highway driving I think this gives me around an extra 1 MPG. Don't see as much benefit for in town driving. Based on temp guage (for what thats worth) looks like the engine runs a little cooler - used to run a touch above 210 before now run a touch below. Don't really notice much power difference.

Just wanted to post this here for anyone looking for how to shorten the Ford Windstar Airbox, as mentioned earlier in the thread. This is how I did it anyways. Background: Airbox is out of a 97 3.8L Ford Windstar, picked it up at a local salvage yard. I put it into a 2006 LJ Wrangler.

I took the part of the airbox that the MAF sensor used to be in, and cut out the middle section.



Then, I cut a few short tabs out of some sheet metal and bolted the two new halves together. I used some ducting tape (the metal kind) to seal the inside.



Then I used some epoxy to make sure it was sealed well.



I finished it off by trimming off the extra bolt threads and using more tape around the outside.



After that, the install was just about the same. I went ahead and picked up some 3 inch flex tubing from Autozone (in the ricer section I believe) and two hose clamps. This let me use the flex tubing to go through the firewall which gave me better access to the dipstick.

Temperature of the intake air is not going to affect the coolant and engine operating temperature

If you are deep enough to fully flood the cowl then yes you will have a problem, but absent that as long as you keep your cowl drain clear seems highly unlikely to me that enough rain water or splashing water could get in there to cause a problem. My intake comes through the firewall offset a little from the vent, it is obviously at a right angle to the way water would enter through the vent, it is off the bottom of the cowl a little and any water that does get sucked in has get through the filter also. I did go ahead and put a cover over the cowl vent (facing the windshield) but I don't think it was necessary. Versus stock location seems to me much less likely to flood.

Nice! This is my next mod to prepare for the front fender lift. Sucking air from the cowl can only help. I've seen IATs in excess of 170F when moving slow in high heat. That will kill your power when the ecu pulls gobs of timing. Sucking air right off the bottom of a black hood, with hot radiator air blowing on it is never good. You will get a somewhat cowl effect at speed with the new intake design.

Picture of cover over the cowl vent?

Don't have a picture here at work, but this the cover I used: http://www.quadratec.com/products/13006_602.htm

My jeep is black so it doesn't really stand out like the pictures on Qtec.
