Cold Air Intake for GMC / Chevy Pickup & SUV (2007-2008) 4.8L 5.3L 6.0L 6.2L V8 Engines

Sport Air Intake System for Cadillac Seville SLS / STS 4.6L V8 – Better Throttle Response, HP & Torque 

Personalized to unlock the hidden performance of your Cadillac's engine, this induction system focuses on giving you more total output. Custom-built for the 4.6L V8 Northstar engine, this kit replaces the restrictive factory air box and intake tube that often limits your vehicle's potential. Whether you are keeping things stock or looking to improve your power, this performance upgrade provides a smooth path for air to reach the engine, leading to a more assertive and capable driving experience.

Standard intake parts are often designed for silence, creating internal blocks that limit the engine's air supply. By utilizing lightweight T-304 aluminum piping to pull in a larger volume of cooler, dense air, this system removes those barriers. This ensures that the engine works more effectively, leading to faster acceleration and a boost in power for your daily driving.

Key Features

• Output Gain: Engineered to boost horsepower and torque by up to 10% for a noticeable increase in performance.
• Premium Construction: Intake pipe made from lightweight T-304 aluminum for durability and heat resistance.
• Open Induction: Replaces narrow factory parts with a high-flow pathway to satisfy the engine’s demand for air.
• Refined Acceleration: Removes the slow feeling of the stock intake for faster acceleration when you step on the gas.
• Efficiency Optimization: Balances air-to-fuel ratios for a more effective burn and better fuel use.
• Sporty Sound: Enhances the vehicle's sound with a deeper intake growl during acceleration.
• Durable Build: Built with premium materials to resist corrosion and ensure long-term reliability.

Vehicle Fitment

This system is designed for the 1998–2004 Cadillac Seville SLS and STS models equipped with the 4.6L V8 engine.

Product Specifications

• Engine Application: 4.6L V8
• System Type: Sport Air Induction
• Tube Construction: T-304 Lightweight Aluminum
• Installation: Direct bolt-on design using factory mounting points
• Filter Type: High-flow washable and reusable performance air filter

What's Included

Your kit features a high-velocity T-304 aluminum induction pipe, a high-flow performance air filter, and all required couplers, clamps, and hardware for a complete and secure installation.

Installation Tip

Disconnect the NEGATIVE GROUND CABLE from the battery before starting the installation and keep it off for at least one minute after you finish. This reset allows the engine's computer to learn the new airflow induction settings. Ensure the engine is completely cool before beginning work.

Performance Cold Air Intake System with Heat Shield – Improved Torque for 2007–2009 GM V8 Engines

Upgrade your truck or SUV’s performance with a cold air intake system engineered to improve airflow, throttle response, and overall driving enjoyment. Designed specifically for select GM full-size vehicles equipped with 4.8L, 5.3L, 6.0L, and 6.2L V8 engines, this intake replaces the restrictive factory air box with a free-flowing system that helps your engine breathe more efficiently.

Standard intake assemblies prioritize quiet operation over raw efficiency, creating internal turbulence that starves the engine of power. By drawing in cooler, denser air and isolating it from engine heat using an integrated heat shield, this system helps unlock measurable gains in horsepower and torque—up to 10% under optimal conditions. The result is quicker acceleration, smoother power, and a noticeably deeper, more aggressive engine sound when you step on the throttle.

Key Features & Performance Benefits

• Power Gains: Increases horsepower and torque by up to 10%, providing a significant boost for the 5.3L V8 and other GM powerplants during towing or highway passing.
• Thermal Isolation: The integrated heat shield protects the air filter from hot engine bay temperatures, ensuring a cooler air charge for maximum combustion efficiency.
• Durable Construction: Built with high-quality induction piping designed to withstand high-heat environments and maintain consistent airflow velocity.
• Enhanced Sound: Provides a more authoritative and mechanical engine growl during hard acceleration, letting your V8 roar.
• Optimized Filtration: High-flow filter media blocks harmful contaminants while maintaining the high-volume air requirements of large displacement engines.
• Efficient Driving: Improved air intake characteristics often result in sharper throttle sensitivity and overall engine responsiveness.
