Default Underhood Heat and Pressure Dissipation

It has been discussed much in other threads about the hood lifting at highway speeds and has been corrected by adding a hose under the seal to stiffen it and to remove the hood lift spring, which pretty much takes care of it, unless you take the plastic underbumper air dam off and it will dance again. On another note, this Wrangler has intense underhood heat, more than I have had on any other vehicle, especially for me since I have hedders. I began looking for some way to releive the pressure building up under the hood in the way of venting the hood that would both be functional and not look bad. As I searched I found that this is not new to the Jeep world (I am new to the Jeep world). I found where a lot of folks have taken the vents from the hood of 1994-1996 Pontiac Grand Prix GTP and put them in Jeep hoods, which don't look too bad. I then found a guy on EBAY selling some long skinny vents to go in the side of the hood on 1987 to 2006 Wranglers
(//cgi.ebay.com/ebaymotors/Jeep-Wrangler-side-hood-louver-air-vents_W0QQcmdZViewItemQQcategoryZ36475QQihZ009QQit emZ190146021509QQrdZ1QQsspagenameZWDVW). However I don't think they will fit on the 2007 Wrangler because there is not enough flat area on the side of the hood. I will know in a few days since I went ahead and bought them. Has anyone else had any experience with doing this venting on the hood of a Wrangler and did it help?

I've seen that hood, I just can't warm up to the look, but thanks. I would like to have their side vents though.

Why does AEV vent the front of the hood by the radiator vice venting the rear of the hood where the most heat is generated, unless they are counting on the LP zone forming under the jeep to suck the heat out of the engine compartment?

Ahhh... Something that I have worried about. I also think that it does not have enough air flow under the hood. I personally like the look of the aftermarket hood better than the side vent. It just does not look right to me. However on my black JK it would be less noticeable.

Just called Pontiac and the GTP vents are discontinued but I found a couple of sets up for sale on EBAY. All the newer hood vents I can find are molded plastic stuck on with 2 sided tape, I want better quality than that. Anyone have any suggestions on quality bolt on vents that would look nice and not be too big?

I've always been partial to basic louvers, it would be easy to put a row on a couple of pieces of sheetmetal and either poprivet/bolt on the top or backside of the hood, or fair them into the hood sides.

LOL, it would almost look like gills.....

You could put a forward facing set on the front and a rear facing set on the back....lots of air flow then!!

Default Take a look at this

I know it is not a JK but I don't think there would be that much of a difference. .oman4x4.com/hoodvents.htm

I have been think about doing this style mod myself.

That is the original link I found that got me headed down the path for the GTP vents. I am convinced that it would be a great benifit to get rid of the pressure and heat.

I would think the hood vents would perform better, I just can't bring myself to cut into the JK.

Just drove home today after buying some wire loom to wrap my fog light wires and raised the hood to be able to access some of the wiring and WOW! It is extremely hot in there. A lot more so than any other vehicle I have owned. I could'nt touch anything for any length of time. I bet we start seeing things break down in a couple of years due to this! Maybe the AEV Hood is in order!
