Hummer H3 Hood Louvers – They cool down  the engine. . . and look great, too! Hot air rises — let it out.  Police report underhood temp drop of 47 degrees!  More efficient engine cooling — and cooler  A/C!  Used for years by the U.S. Border Patrol and Law Enforcement agencies across the country — so you know  they work!

Choose from Powder-Coated Black or White or Natural Aluminum.  Come with pop rivets, drill bit and full home-install instructions.

“These were great quality and finish and a breeze to install.  They remove a huge amount of under-hood heat.  Parking it after a hard run you can see and feel the heat pouring out of the louvers!  The H3 has a perfect area on both sides of the hood with no supports just smaller than the louvers.  Thanks for a great product!”

“It looks and fits GREAT!  They dropped the engine temperature on the gauge 15 – 20 degrees.  Their quality is great.  Excellent work!  This is what GM should have done on the H3 in the first place!  The instructions are real clear and straightforward.  I’m so pleased I am going to buy another set of your hood louvers for my Jeep!”

“Received my hood louverFriday and installed it today.  Love it!  I’ve hated that fake (factory) plastic hood panel from day one, but had limited options.  Took a shot with you guys and couldn’t be happier.  Thanks for a product that satisfies form and function.”

“This louver has gotten more attention than just about any other mod I have made!  I have a lot of Hummer guys already asking for your info as well as Jeep guys and other truck guys on my team.  I drove from San Antonio to Corpus today and the difference is immediate and fantastic!  I not only saw a lower engine temp on the drive but an amazing improvement at the beach!  We played in the sand for hours today and the truck never passed the 1/2 point!  Your product exceeded everything you said and more.  Installation was as straight forward as could be.  I followed the instructions and in about an hour the job was completed.”
