Product Description

The K&N 57-3058 Cold Air Intake is a performance-oriented upgrade designed for 2007-2008 full-size Chevy, GMC, and Cadillac trucks and SUVs equipped with V8 engines (4.8-6.2 L). By replacing the factory airbox and restrictive intake with a high-flow, smooth-path HDPE intake tube and oversized oiled cotton-gauze filter, this system allows your engine to breathe easier - drawing in cooler, denser air for improved combustion. The result is a dyno-proven horsepower increase (typically around +17.5-18 HP), stronger torque, sharper throttle response, and a more pronounced V8 engine note under throttle.

Thanks to the washable, reusable filter and durable HDPE construction, 57-3058 offers long-term reliability and low maintenance. The included heat shield helps shield intake air from engine-bay heat, preserving performance under load, towing, or high ambient heat conditions. Installation is entirely bolt-on - requiring only basic hand tools and roughly an hour - making it a practical upgrade for truck and SUV owners who want meaningful performance gains without complicated modifications. The intake is CARB-compliant when installed on approved vehicles and includes all necessary hardware, making 57-3058 a dependable and street-legal choice for owners of 2007-2008 Silverado, Sierra, Tahoe, Suburban, Yukon, Escalade, Avalanche and related models.
