yes
this is the short 3 piece set from Gen-Right I think it was $75+shipping even comes with rivets
cut the hood with a jigsaw
the thing I dont care for is the one in the front throws mud and water right on the windshield from the fan

That is not a good thing! :shock:

No way to stop it?

I think I am going to order some of those this week. They are nice and by far the cheapest I've seen around.

Would hood louvers help at all? Wouldn't they let some of the heat escape the engine compartment?

Yes and they have lowered my temps a few degrees.

Hey troy,

I was wondering how much clearance you found you had between the hood and the top of the engin?

Reason i ask is I was wondering if it would be possible to , SOMEHOW, rig up some small fans like the type, but not neccessarily the same, as the ones used in the back of computers to actually draw air accross the engine and be more of an active cooling rather than a radiant passive. Those louvers look great, but i wonder if you could boost the air flow through them with a couple of those fans under each louver inside the hood and set to activte off the same circuit as the radiator fan. Just a quick thought I had. some of those fans move a butt load of air and are, by design, pretty compact.

Jason, how hard was it to cut the hood? I am not ashamed to admit, I am terrified of cutting holes in my hood. :shock:

If I screwed up, I'd be screwed.

Just a thought in case you want to go with the Muscle Car look, Stylin Conceptes have hood scoops you can make small holes for venting with less colateral damage. Just Exit ports for heat to escape with less hole cutting:

Who wouldn't want a Shaker Hood on a KJ :twisted:

Much easier than I thought
Like I said I used a jigsaw also used a BUTT load of painters tape some news paper and lots of time
the first one was the hardest ,emotionally, but after that it was easy
I marked each hole ,#2 pencil is not a great idea wax pencil would have been better, based off of center
I used the sprayers to find center and went from there
I lined each hole with tape and cut on that line also changed the blade for each hole
The one thing you need to watch for is that you do not cut the support ribs

For the KJ I would get either the 2 pcs short or 2 pcs long but not the 3 pcs
I did not care for the way the long front one fell on the hood ,you know I placed them up there to have a look
should have taken a picture
You will also need a rivet gun they come with rivets
remove the hood and place it on some saw horses to make life easier
and make darn shore you cut the holes 1/2" all around smaller than the louver
I think it took maybe 3 hours off and back on the Jeep
I may do the KJ when it becomes my DD ,worth the gain and when I do get the KJ it will be old and have close to 100K on it ,it is pushing 5 years old now so it will be 7+ by the time I get to "cut it up"

Terry

HAHA
it is not that bad kinda get a fin dirty mist when I hit a deep muddy hole
remember I HATE MUD so I avoid it at all cost
I will got through the woods and get all kinds of scratches rather than go through deep mud
oh and I fixed my sprayer so I can wash the window
heck it blows water in the rain if I rev up the engine ,takes about 3K rpm or so to do it
as far as stopping it that would also stop air flow so I dont want to

Cutting the hood is the easy part, nothing too it, drill holes at all four corners, and cut away, I used painters tape as well about 3 or 4 layers and a jig saw, took maybe 3/4 minutes or less each. Actually was sort of fun knowing that it would be different ( for a while :roll:

)

For Woody, as far as getting more air flow small fans would only work to a point I think, much more trouble than it would be worth but there is quite a bit of room from the bottom of the hood to the engine

I have received a lot of positive comments about mine so far even from some Wrangler owners and a Grand owner, although they were all the same OH I COULD NEVER CUT INTO MY HOOD!!!!! :lol:

Just installed my Louvers today. I got them from a local shop called Totally Offroad. They are the Gen-Right ones. They let a ton of air blow out. I was really shocked when I stuck my hand in front of them and felt a hot rush of air.

You see what I see?

Scroll down

Still don't see it?

That's right

The answer to our "Cold Air Intake" question, while having heat escape.

mmmmmmmmmmm Since the hood is being cut up.....

Finish your thought. Or did I miss something?

flip that one over the air box around and use it as a scoop? :shock:

correct. move it down flip it over and put it right over the air box.

You guys need to scroll down to the whole message. don't be so impatient. take your time, read all the way down.

Wonder what using one of them as a cold air intake ram would do?

tommudd · **Posted:** Tue May 20, 2008 1:34 pm

Would have to determine a way to keep the air filter away from all the moisture that would be shoved into the area.
I have some drawings of a filter set up that may work with this.
Could have the air coming into a main air box, with a cone type filter set behind a panel (blocking most of the moisture) cone filter would be (for a better term sitting in like a one gallon paint bucket) with the hose coming out of the bottom heading for the engine. All could be made to fit the same area that the stock box now takes up.
My mind works in mysterious ways at times so

I draw things as they come up so bear with me .......

It could work quite well, need to se how much air would actually be captured at that point on the hood

I like the look of the louvers on the sides of the hood... Too bad that only works for the flat hooded Libertys.

Tom, where did you get your louvers again?

used ones off of a Pontiac GTP they are the 5 louver , they used both 5 and 9 louvers on the GTPs depending on the years , 9s are too long though. I like them cause they work and are cheap :wink:

Thanks. I'll start looking for some now that the Jeep has been set aside from daily driving duty. (Time to play)
