WCFab High Flow Intake Bundle Kit for 2020-2025 Chevrolet/GMC 2500/3500 HD (6.6L) - Gloss White - WCF100414-GW

The WCFab High Flow Intake Bundle Kit for the 2020-2025 Chevrolet Silverado and GMC Sierra 2500/3500 HD (6.6L L5P Duramax) is a comprehensive airflow solution designed to eliminate the restrictions of factory intake and intercooler plumbing. This kit replaces the narrow OEM intake and the leak-prone plastic/rubber intercooler pipes with heavy-duty, oversized aluminum components for improved durability and optimized flow.

• Air Intake: Includes a 4 in. mandrel-bent aluminum intake pipe, air box enclosure, and dry filter assembly with a hydrophobic Outerwears pre-filter cover. The 4 in. intake horn features a PCV port and surge ring.
• Intercooler Piping: Upgrades the hot side to a 3 in. diameter 1-piece pipe and the cold side to a 3.5 in. diameter pipe. The 3 in. hot side pipe eliminates the restrictive OEM clip ring at the Y-bridge in favor of a silicone boot and T-bolt clamp for a leak-free seal under high boost.
• Construction: All pipes are fabricated in the USA from 14-gauge aluminum with smooth mandrel bends and finished in a Gloss White powder coat.
• Components: CNC machined flanges with double O-rings, high-quality silicone boots, stainless steel T-bolt clamps, and all necessary installation hardware.

This kit is a direct bolt-on upgrade that retains factory connection points and sensors. No aftermarket tuning is required for installation. Part Number: WCF100414-GW.
