Hummer H3 Testimonials
Hummer H3 Hood Louvers – They cool down the engine. . . and look great, too! Hot air rises — let it out. Police report under-hood 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!
Available in mirror-polished Stainless Steel — looks just like Chrome! Also choose from Powder-Coated Black or White or Natural Aluminum. Come with pop rivets, drill bit and full 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!”
Brett H. – Kansas – Hummer H-3
“It looks and fits GREAT! They dropped the engine temperature on the gauge 15 – 20 degrees. They 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 our hood louvers for my Jeep!”
