Cold Air Intake Kit - GMC Sierra 1500/2500/3500 (1999-2006) V8

Built for America's Workhorse

Your GMC Sierra has earned its reputation as one of the most dependable full-size trucks on American roads. Whether you're hauling equipment to the job site, towing a trailer, or tackling weekend adventures, your Sierra's V8 engine provides the reliable power you count on. But the factory intake system holds back that potential, using restrictive components designed more for cost efficiency than performance.

This cold air intake kit changes everything. Engineered specifically for the 1999-2006 Sierra with 4.8L, 5.3L, and 6.0L V8 engines, it replaces cramped factory air filtration with a high-flow system that feeds your engine the cool, dense air it's been craving. The result? Up to 10% gains in horsepower and torque that you'll feel whether accelerating onto the highway, climbing mountain passes, or hauling heavy loads.

Professional-Grade Performance Engineering

• Up to 10% Power Increase - Unlock hidden horsepower and torque for stronger acceleration, better towing capability, and improved passing power
• T304 Aluminum Construction - Lightweight, corrosion-resistant piping provides durability for years of reliable service
• Superior Filtration Technology - High-flow filter delivers exceptional airflow while protecting your engine from harmful contaminants
• Enhanced Throttle Response - Experience immediate power delivery the moment you press the accelerator
• Improved Fuel Efficiency - More efficient combustion means better mileage during highway cruising and daily driving
• Deep, Sporty Sound - Maximized airflow through the stock manifold creates an aggressive V8 tone under acceleration
• Low-Maintenance Design - Washable filter requires cleaning only every 50,000 miles under normal conditions
• Complete Bolt-On System - Direct replacement for factory airbox and intake tube—no cutting or modifications

Maximum Airflow, Minimum Maintenance

Unlike disposable paper filters that require constant replacement, this cold air intake features a premium washable filter that delivers consistent performance for up to 50,000 miles between cleanings. The high-flow design maximizes air volume while the advanced filtration media captures harmful particles, protecting your engine while unleashing its full potential. The T304 aluminum piping resists corrosion and heat, ensuring long-term reliability even in demanding work-truck conditions.

Simple Installation, Impressive Results

Transform your Sierra in under 60 minutes using basic hand tools. This complete kit includes everything you need for a professional installation: T304 aluminum intake pipe, high-flow washable air filter, mounting hardware, and all necessary clamps and couplers. Direct bolt-on design replaces your factory airbox without cutting or fabrication.

Installation Tip: After completing installation, disconnect your battery's negative terminal for 30 seconds. This allows your engine computer to recalibrate and optimize performance with the increased airflow.
