Cold Air Intake Kit for GMC Sierra 1500/2500 Classic Edition (2007) with 4.8L / 5.3L / 6.0L V8 Engine

Unleash the hidden growl of your Vortec V8 and finally fix that sluggish throttle response on your Silverado/Sierra Classic.

High-Flow Cold Air Intake System for 2007 GMC Sierra 1500/2500 Classic (GMT800)

If you’re driving a 2007 "Classic" Edition, you’re likely still dealing with that massive, restrictive factory plastic resonator box. This kit replaces that bulky "accordion" tube and muffled air box with a high-velocity T304 aluminum intake track.

Since the 4.8L, 5.3L, and 6.0L variants all share the legendary Gen III Small Block architecture, this kit provides a precision seal for all three displacements. It eliminates the intake turbulence that usually makes these trucks feel "heavy" when merging onto the highway or towing uphill.

Technical Specifications

Why You Need This Upgrade

• Throttle Response: Deletes the factory baffles to eliminate "dead pedal" lag during heavy acceleration.
• Engine Soundtrack: Swaps the silent plastic air box for a deep, aggressive V8 growl under load.
• Thermal Management: Lightweight T304 aluminum piping offers superior heat dissipation compared to stock composite.
• Long-Term Savings: Includes a washable, reusable filter that lasts 50,000 miles between cleanings.

Installation & Fitment Notes

This is a straightforward driveway install that takes less than 60 minutes with basic sockets and a screwdriver. We highly recommend disconnecting your battery for 15 minutes during the install. This forces the PCM to "re-learn" the new, increased airflow parameters for maximum gains.

Ditch the restrictive factory baffles today and let your Vortec V8 breathe the way GMC intended.
