DESCRIPTION
Product Overview
- The GM GMT800 truck and SUV platform powered by the legendary 4.8L, 5.3L, and 6.0L Vortec V8 engines is built for heavy towing, daily driving, and off-road reliability. However, the restrictive factory air intake and baffled tube choke airflow, stifling throttle response and hiding your engine’s true horsepower.
- The Performance Cold Air Intake System replaces your restrictive stock intake box with a smooth, high-flow 4" intake tube and heat shield enclosure. By drawing denser, oxygen-rich ambient air into the intake manifold, this kit improves combustion efficiency, sharpens throttle response, and gives your LS-based V8 a deep, aggressive roar under acceleration.
Key Features
- High-Flow Tubing: Replaces the restrictive factory intake pipe with a smooth, mandrel-bent 4" diameter intake tube to maximize CFM air volume and airflow velocity into the throttle body.
- Powder-Coated Heat Shield: Includes a heavy-duty steel heat shield that isolates the air filter from hot engine bay temperatures, ensuring only cool, dense air reaches the engine.
- Washable High-Flow Dry Air Filter: Features a reusable, high-performance conical air filter that provides superior filtration while increasing air volume into engine.
- Enhanced Engine & Intake Sound: Eliminates factory intake resonators to unleash a deep, muscular intake growl under hard acceleration without drone while cruising.
FAQ
Q: What are the main performance benefits of upgrading from the stock intake to this 4" cold air intake?
A: The restrictive stock airbox and narrow, baffled tubing slow down airflow. Upgrading to this 4" mandrel-bent system significantly increases air volume (CFM) and velocity into the intake manifold, delivering sharper throttle response and increased horsepower and torque.
Q: Is upgrading to a high-flow dry filter better than keeping the stock paper air filter?
A: Yes. Factory paper filters quickly clog and restrict airflow. The included high-flow dry filter maximizes air volume, traps dirt effectively, and is 100% washable and reusable—saving you money on replacements over time.
Q: Do I need a custom ECU tune after installing this 4" cold air intake?
A: No, custom tuning is not required. The intake operates safely within your stock MAF sensor parameters, though pairing it with a tuner will maximize horsepower and torque gains.
Q: Will this intake fit if my truck has a throttle body spacer or mechanical fan shroud?
A: Yes. The kit accounts for factory fan shroud clearance, and the flexible silicone couplers allow easy adjustment along the 4" tube if a throttle body spacer is installed.
