Cold Air Intake for Chevy Colorado Canyon H3 H3T (2007-2012) 3.7L Engine - Red

Stop letting your Atlas-family inline-five struggle for breath through a restrictive, heat-soaked factory air box and reclaim the throttle response your truck deserves.

Performance Cold Air Intake System with Heat Shield for Chevy, GMC, and Hummer 3.7L (LLR Engine)

If you’re driving a 3.7L Colorado, Canyon, or H3, you know the "Atlas" inline-five is a unique beast, but the factory intake tract is doing it no favors. The stock plastic resonator box is designed for silence, not flow, creating turbulent air and trapping heat right over the cylinder head. On the forums, the consensus is clear: the 3.7L LLR engine thrives when you smooth out the induction path and drop the intake air temperatures (IATs).

This kit replaces that bulky OEM plastic with 3-inch 6061-T6 premium anodized aluminum piping. Unlike the factory corrugated rubber hoses that create "drag" in the air column, these smooth-bore pipes ensure a high-velocity laminer flow directly to your throttle body. By utilizing the included heat shield, you isolate the high-flow micro cotton filter from the engine's radiant heat, ensuring the air entering your combustion chamber is as dense and oxygen-rich as possible.

Whether you're crawling in an H3 or hauling in a Colorado, this upgrade solves the "lazy" throttle feeling inherent to the electronic throttle bodies on these GMT355 and GMT345 platforms. We’ve included the specific MAF sensor adapter to ensure your fuel trims stay within spec, meaning you get the horsepower gains without the headache of a "Check Engine" light.

Why You Need This Upgrade

• Smoother Throttle Response: Eliminates the factory intake resonator to provide instant air delivery when you tip into the gas.
• Thermal Management: The dedicated heat shield prevents the air filter from sucking in hot air from the radiator and exhaust manifold.
• High-Flow Filtration: The washable chrome mesh micro cotton filter offers superior surface area compared to paper filters, increasing CFM.
• Durable Construction: 6061-T6 Anodized Aluminum resists corrosion and won't crack or warp like the aging factory plastic components.
• Engine Health: Includes a dedicated air breather filter for the vacuum hose to maintain proper crankcase ventilation.

Installation Notes

This is a direct-fit kit that installs onto your factory throttle body. No additional parts, cutting, or drilling are required for installation. Ensure you clean the MAF sensor with specialized cleaner before transferring it to the new adapter to ensure the most accurate readings. Basic hand tools are all you'll need to complete the swap in your driveway.
