Wehrli WCFab High Flow Intake Bundle Kit for 2020-2025 Chevrolet/GMC 2500/3500 (L5P Duramax) - Gloss Black

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

The WCFab High Flow Intake Bundle Kit is a comprehensive Stage 1 upgrade designed to eliminate the restrictive and failure-prone factory piping on the L5P Duramax. This kit replaces the 2.5-inch factory hot side pipe and the multi-piece plastic/rubber cold side pipe with heavy-duty aluminum components to optimize airflow between the turbo and the engine. By removing the OEM resonator and secondary boot joints, this bundle improves efficiency, throttle response, and turbo spool-up.

Engineered for high-performance and heavy-duty applications, these pipes are manufactured in the USA from 14-gauge mandrel-bent aluminum. The 3.5-inch passenger side pipe features a CNC-machined flange with a double O-ring seal, replacing the weak OEM clip ring design at the Y-bridge with a robust silicone boot and stainless steel T-bolt clamp connection to handle increased boost pressures without leaking.
