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

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

The WCFab Stage 2 4in Intake Kit replaces the restrictive factory plastic intake components with a high-flow fabricated aluminum system designed to maximize turbo efficiency. This kit features a 4-inch diameter intake pipe and an oversized 4-inch intake horn that is over an inch larger than the OEM inlet, significantly reducing intake restriction. The included air box and lid are constructed from heavy-duty 10-gauge aluminum sheet and feature a custom seal that connects directly to the functional hood ram air port and inner fender duct for a steady supply of cool, dense air.

Built for durability and performance, this bolt-on system requires no tuning and utilizes high-quality silicone boots and stainless steel T-bolt clamps for secure connections. The assembly is finished in a durable Gloss Black powder coat. This kit replaces GM Part Numbers: 84841229, 84841225, 84262962, 85614333, and 84554702.
