I have seen pictures of people useing older body style Pontiac Grand Pre hood louvers and reportedly with good results and they look good although they are somewhat pricey if memory serves. Try searching here or google for jeep hood louvers.

Later,

I know a few ppl have used LeBaron hood louvers/vents.
They are fairly cheap too.

SaddleBronc · 08-23-2005, 08:36 PM

I have the ones from an 88 LeBaron Turbo on mine. It really makes it stand out but does nothing for getting rid of the underhood temps. I want to find a place that will stamp the louvers into the hood it self like on the ole' muscle cars of yester year. I think that would help alot by forceing air down on top of the motor but really only on the highway. The money I have spent in the vents as well as time, I wish I could have just spent the money on a bigger better radiator and a set of be cool fans or something. Good luck!

I went to one of the local ricer speed shops. Told them what I was lookin for and after looking through some of their books came across some 4x6 abs louvred things. Cut out my fender and just attached these. Cost like $25.

rioshilo · 08-24-2005, 07:05 AM

I used vents from an older 280Z...

lilgreenjeepyj · 08-24-2005, 07:15 AM

My question is, do they work???

planefixer · 08-24-2005, 07:16 AM

I'm using some aircraft vents--good sturdy aluminum

Temps decreased only about 4-6 degrees but every little bit helps.

sceep · 08-24-2005, 07:48 AM

remove your inner fenders and forget about hood vents.

my water temp dropped almost 25 degress when i pulled the inners out.

I dont know how much you spent on your hood vents but u must have got ripped off if you could have spent that money on a new rad and fans... I also have LeBaron hood vents got em for $30 and thats cus i was lazy and didnt pull my own. Spent all of 2 hours to install them.

stupidfast · 08-24-2005, 08:22 AM

in 4WOR recently they had an article on hood louvers on an xj. they put them twards the back of the hood so any water wouldnt drip through to get onto anything it could hurt. they took temp readings before and after on important parts like the radiator and head and some others, and they all dropped 20*. they were a good size too. two of them about 12"x16" maybe.

mcjeep84 · 08-24-2005, 08:32 AM

I used Lumina Z34 vents to be different. They work great for low speed crawling which is where I was having problems, I can watch the heat rising out of them. Got me down 15-20 degrees.

Hood Vent Write Up

Dirk00TJ · 08-24-2005, 11:31 AM

I did some vents from a early 90's model Pontiac Grand Prix GTP Turbo. They are the biggest vents I've seen, but they are pricey at the delaer. They do let out a good deal of heat though. Here's a pic:

I had a fully louvered hood on my XJ. Something like 200+ Louvers, IIRC. Underhood temps were nice and cool down was much quicker.
Neither of these options is especially cheap though.

RkCrlr · 08-25-2005, 06:57 AM

Have 2 for now will do 4 tho.

soup4856 · 08-25-2005, 07:14 AM

With a 5.0 in an XJ I have been fighting heat the whole time. The best thing I did was rap the headers. If the engine has been idleing for 5 mins I can still reach down and touch the headers. Then I put a couple spacers at the hood mounts and lifted the rear of the hood about a 1/2 inch. Nobody notices and you can feel the heat rolling out the back of the hood.

have you ever cracked a header?

microtus · 08-26-2005, 05:26 AM

Somebody in the Quadratec bb did a rather extensive tech post on hood vents about a year ago. Listed real numbers with underhood temps, air movement ect ect for the different areas under his hood...IIRR he pirated some hi teck equipement from work to do the testing. 0525 in the morning and my commute begins....With any luck I'll take a look for it this afternoon and post the link.

keifer · 08-26-2005, 06:46 AM

I priced the iroc-z louvers this week new from the dealer is $82. Looks like pic and pull for me.

That was the link WebJeep posted or at least it was linked to.Here it is. I agree that it was a VERY well written and researched article.

microtus · 08-26-2005, 03:43 PM

That link isn't working for me Navy. I originally thought it was from Quadratec but just found it on JU.

Here is the JU link.
