KAX 3.75 inch Cold Air Intake System Kit & Heat Shield Replacement for Hummer H2 2003-2009, High Performance, RED

What the 3.75” Intake Actually Changes

This isn’t your typical small-diameter intake. The 3.75-inch piping significantly increases airflow capacity compared to stock, helping your engine breathe easier under load.

• 3.75” large-diameter intake pipe for maximum airflow

• Cold air design to bring in cooler, denser air

• Heat shield included to reduce engine bay heat soak

• Improved throttle response (especially noticeable on a heavy SUV)

• Deeper, more aggressive intake sound

• Red high-flow filter for performance and visual impact

It’s not turning your H2 into a sports car—but it will make it feel less restricted.

Why the Heat Shield Matters (Especially on a Big V8)

Under-hood temps in an H2 can get… spicy. The included heat shield helps isolate the intake from engine heat, which means:

• Cooler intake air temperatures

• More consistent performance

• Better efficiency under load

Without it, you’re basically upgrading airflow just to inhale hot air. Not exactly winning.

[High Performance] : The Cold air filter intake kit can help your engine to draw more cold air resulting in better throttle response and higher explosive horsepower output.[Package included]:1 x Air Filter, 1 x Air Intake Tube, 2 x Silicon Hose, 2 x Silicon Connecter, 1 x Filter Heat Shield, All accessories on the picture are included

The Red Filter: Function Meets Attitude

Let’s be honest—this isn’t a subtle vehicle, so why go subtle with the intake?

Real-World Benefits You’ll Notice

You’re not chasing dyno numbers here—you’re improving how the vehicle feels:

• Better throttle response when accelerating a heavy SUV

• Improved airflow efficiency under load

• More aggressive intake sound

• Slight gains in overall performance feel

Basically, it helps your H2 feel a little less like it’s dragging a house behind it.

Why This Upgrade Makes Sense

If you’re driving an H2, you already accepted the trade-offs—size, weight, and fuel consumption. This intake helps balance that by improving airflow and responsiveness where it matters most.

And honestly, if you’re going to drive something this big… it should at least sound like it means it.
