After suffering with high temps again this summer I ordered some hood louvers from www.hoodlouvers.com . Took a week to do it at work on breaks and wouldn't ya know it, when I get them in place the temps drop from over 100 to mid 80's to 90's and rain for the past couple of days! At least I can report that the vents are in a good place for air over the hood to pull air out on the hwy from the path of the rain drops up the hood. Yes, I know- only 4 rivets holding it on, did I mention it has been raining on and off? That will be fixed tomorrow. Just wish I could have had some higher temps to see how much it cools now, maybe later in the week.

 

Can you post some pictures of the under side of the hood?

I like your setup.

 

I like the look.

 

Or is it an aftermarket company, my Alpha ran hot this summer but it was over 100 out and I was towing a lot. Interested to see if this works.

 

Temps only reached 90 again today. Why does it have to be so unseasonably cool outside?!? I haven't noticed a big difference so far, but the temps haven't been too high yet either. I feel the heat coming out of the vents when stopped, see the temp guage take (maybe?) a little longer to rise in city traffic but that could be due to being cooler outside. I can also see where the rain comes over and around the vents that there is a good negative pressure airflow in the area.

Here are the pics of the underhood and outside I took as soon as I had it tacked on for a test drive. I wish the vents were about 1/2-3/4 inch narrower to fit the cutout under the hood better- I wanted to keep all the rivets inside that area I cut out and not rivet through multiple layers of hood sheet metal.

 

it's just generic aftermarket. They have various sizes and can do custom orders too. I believe I have the 9"x14" size.

 

did they come painted or did you do that?

where did you get them from?

 

They come natural, polished or painted black. I figured that I can paint and saved a couple bucks there by getting mine unpainted. Gave it a light sandblast for texture and sprayed it with Rustoleum bed liner from a spray can (almost idiot proof) for a nice texture on the top and a semi-gloss on the bottom.

The hardest part was drilling the first hole for the body saw.

 

Why not order the model they have for the H3 that replaces the fake plastic louver?

 

The only functional louver I have seen that replaces the plastic panel in the center of the hood weighs significantly more than the hood strut can handle by itself and I didn't want to have to screw with that detail. (or add that much more chrome) I also am not sure that I wanted a hole right over the coil packs that could allow water to leak into a known problem area. The holes I cut out are above the air filter housing and the fuse box which is fairly water resistant and easy to mount a tray over to divert water if needed.

Besides, I did it 'cuz I could and no-one else had. (and I also live in an area of the country that doesn't get a lot of rain)
