Wehrli Custom Fabrication High Flow Intake Bundle Kit for 2020-2025 Chevrolet/GMC (6.6L) Illusion Cherry - WCF100414-RED

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

This Wehrli Custom Fabrication (WCFab) High Flow Intake Bundle Kit is a comprehensive air management upgrade designed to replace the restrictive factory intake and intercooler plumbing. By increasing the turbo inlet diameter to 4 inches and replacing the plastic/rubber OEM components with heavy-duty mandrel-bent aluminum, this kit optimizes airflow and significantly improves durability under high boost levels. The system is designed to bolt directly to factory mounting points and retains all OE sensors without the need for aftermarket tuning.

The package includes a Stage 2 intercooler pipe upgrade, replacing the 2.5-inch resonator-equipped driver-side (hot) pipe and the leak-prone 2-piece passenger-side (cold) pipe. The new 1-piece 3-inch hot-side and 3.5-inch cold-side pipes utilize CNC-machined flanges with double O-rings and high-quality silicone boots with stainless steel T-bolt clamps to eliminate boost leaks and ensure a secure connection even in high-performance applications.
