WCFab High Flow Intake Bundle Kit for 2020-2025 Chevrolet/GMC Silverado/Sierra 2500/3500 HD (6.6L L5P) - Gloss White - WCF100410-GW

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

The WCFab High Flow Intake Bundle Kit is a comprehensive Stage 1 cooling system upgrade designed to eliminate the restrictive and failure-prone factory plumbing between the turbo and the engine. By replacing the undersized OE plastic and rubber components with high-flow aluminum piping, this kit improves throttle response, turbo spool-up, and overall engine efficiency. The 3-inch hot-side pipe replaces the restrictive 2.5-inch factory unit and deletes the resonator for smoother airflow, while the 3.5-inch cold-side pipe replaces the weak plastic OE pipe known for boost leaks and failures under load.

Each component is manufactured in the USA from heavy-duty 14-gauge aluminum tubing featuring mandrel bends for maximum flow. The cold-side pipe utilizes a CNC-machined flange with a double o-ring seal, replacing the factory clip-ring design at the Y-bridge for a superior, leak-free connection capable of holding significantly higher boost pressures. This bolt-on kit requires no tuning and is compatible with stock trucks.
