Wehrli Custom Fabrication Stage 2 4in Intake Kit for 2020-2025 Chevrolet/GMC 2500/3500 HD (6.6L) - Gloss White

Fits 2020-2025 Chevrolet Silverado and GMC Sierra 2500 HD / 3500 HD (6.6L L5P Duramax).

Eliminate the restrictions of the factory plastic induction system with the Wehrli Custom Fabrication (WCFab) Stage 2 4-inch Intake Kit. This system replaces the entire OEM air path with large-diameter, fabricated aluminum piping and a high-flow 10G aluminum air box. Designed to interface directly with the factory hood Ram Air duct and inner fender ports, this kit ensures the turbocharger receives a consistent supply of cool, dense air for improved throttle response and increased air velocity.

The centerpiece of the Stage 2 kit is the 4-inch intake horn, which is over an inch larger than the OEM diameter, removing the primary bottleneck found at the turbo inlet. Finished in a signature Gloss White powder coat, this kit provides a custom look under the hood while maintaining a simple bolt-on installation that requires no aftermarket tuning.
