Gen-Right hood louvers

Anyone have these? http://www.genright.com/ProductInfo....uctid=LVR-1008

I am thinking about getting a set. Last time out on the trail my underhood temp go so high it melted my relay for aux. lights. I couldn't belive how damn hot it got underthere! The relay is mounted on the passenger side on one of the plastic underhood tray bolts right near where the hood and body meet which means it was a close to getting some outside air as I could get it. And it was only 75 degrees in Big Bear at the time!

Check 'em out....If I am going to tear into my hood for the AEV snorkle might as well go all out right? I don't have much of a concern for rain as I am in So Cal, but I want to be strategic about where I put them too as to not cause any undue drama.

I'm waiting on a set of the square ones. If I don't get them installed this week, it will be early next week and I'll post my findings on temps.

And don't forget the pictures. I've been wanting to put in the louvers (since I found out the price of the AEV heat reducing hood ) but there is some discomfort in cutting up my jeep. But I had one of those plastic relays distort in the heat also and in the Dallas heat this summer, I think I've now lost a battery. (Shoot, you'd think a 5 year battery would last more that 21 months.) I had to jump it Saturday, I got the "Low System Voltage" code P0562 later that same day and the engine sounds a bit slow when cranking. Makes me nervous.

So, anyway, let us know what you find. I'm interested!

So I’m not the only one who thinks it gets way hot under the hood? I’ll be interested in this mod.

As a pimp for GenRight we sell many of these louvers for lots of different makes and models of 4X4s. Our test have shown with a 5 piece louver set on a TJ the avg drop in temp is 20 degrees.
Any time you can evacuate the heat under the hood you are way ahead of the game especially on the trail.

Due to the cros braced supports under the hood, putting one of the the wide pieces at the front would not be as easy, but it could still be done. I will see how the two do that I'm going to putting in, then make a decision on whether to add more.

With a IR thermometer I identified four hot spots where the hood gets around 20°F hotter than the surrounding areas. A simple hand in the engine bay will find them also.

1/ Either side of engine above front of manifold
2/ Between radiator and engine
3/ Rear of engine

I will be tackling the areas in 1/ first as these are hottest. Also, when the fan is on, it throws air up to areas 1/ and 2/ the most.

Yes, I think it gets too hot under there too, not only does this make every thing run hot, it can damage hoses, electrical parts, etc.

You guys might also consider a heat wrap on your exhaust manifolds, or a ceramic coated header set.

I carry a set made by JBA if anyone needs a quote.
