Upgrade your vehicle's performance with the K&N 57-3038 High-Flow Cold Air Intake System, designed specifically for select Chevy Silverado and GMC Sierra models equipped with a V6-4.3L engine. This system features a durable, rotationally molded high-density polyethylene (HDPE) tube that helps increase airflow to your engine, resulting in guaranteed improvements in horsepower and torque.

The system is engineered for easy installation, often completed in less than 90 minutes, making it a practical upgrade for enthusiasts and professionals alike.
Included in this kit is a washable, reusable High-Flow Air Filter with oiled cotton media, capable of going up to 100,000 miles between servicing under normal highway driving conditions. This oversized, conical filter design maximizes airflow and filtration efficiency, contributing to consistent engine performance and longevity. Compliant with EPA standards, this intake system is a reliable choice for those seeking increased power while adhering to environmental regulations. The entire assembly is covered by the trusted K&N No-Hassle Lifetime Limited Warranty, offering peace of mind with your investment.
Note that some intakes may not be legal for sale or use on pollution-controlled vehicles in California; please check the product specifications for CARB status and compliance for your specific vehicle. Designed to fit a range of model years from 1999 through 2007, this performance intake system is a versatile upgrade for your truck, enhancing both power output and engine sound while maintaining factory-like quality and durability.
