You may love your Hummer H2 for its ruggedness, roomy interior and raw power on the road, but I'd be willing to bet that with oil prices hovering around $101 a barrel, and gas prices guaranteed to skyrocket this summer, you may be feeling a teensy bit of buyer's remorse. But the thing with Hummer H2 owners, they're loyal. They love the big brutes they drive, but they can't just say to heck with lousy mileage as their Hummer's big V8 sucks down the petrol like so much Krystal champagne. So what's a Hummer lover to do? Well, you could install a Hummer H2 cold air intake. Getting a reputable dealer to install a Hummer H2 cold air intake will not only increase your gas mileage, it'll also give you a big boost to your horsepower. That's right, installing a Hummer H2 cold air intake unleashes the powerful beast lurking inside that hulking mill under the Hummer's broad hood, and it'll save you money in the long run, to boot. Fortunately for Hummer owners, they have a lot of options that they can use that won't void their warranty and are street legal in all 50 states as well. If you want to install a Hummer H2 cold air intake, then you should track down the K&N 57 Series FIPK Cold Air Intake, Generation II, and the K&N 77 Series High Flow Performance Air Intake. These are two of the best options for you to consider if you're getting a Hummer H2 cold air intake.
