WCFab 4" Intake Kit with Dry Filter for 2020-2025 Chevrolet/GMC 2500/3500 HD (6.6L) - Gloss Black

Fits 2020-2025 Chevrolet Silverado and GMC Sierra 2500/3500 HD trucks equipped with the 6.6L L5P Duramax diesel engine.

The WCFab 4-inch High Flow Intake Kit replaces the restrictive factory plastic components with a high-performance fabricated aluminum assembly designed to maximize airflow and thermal efficiency. By utilizing the functional hood ram air duct and inner fender air path, this system delivers cooler intake temperatures and increased air volume to the turbocharger, resulting in improved throttle response and more aggressive turbo sound during acceleration.

Constructed from heavy-duty 10-gauge aluminum sheet metal, the air box and lid provide a robust, heat-shielded environment for the included dry air filter. The 4-inch intake piping features smooth, aerodynamic bends to maintain high air velocity. This is a true bolt-on upgrade that requires no ECM tuning and is compatible with stock vehicle configurations.
