Wehrli WCFab Stage 2 High Flow Intake Bundle Kit for 2017-2019 Chevrolet/GMC (6.6L L5P) - Gloss White - WCF100441-GW

Fits 2017-2019 Chevrolet Silverado and GMC Sierra 2500 HD / 3500 HD (6.6L L5P Duramax).

The Wehrli Custom Fabrication (WCFab) Stage 2 High Flow Intake Bundle Kit is a comprehensive induction and charge-air upgrade for the L5P Duramax. This kit addresses flow restrictions by replacing the factory 2.5-inch hot side and plastic 2-piece cold side intercooler pipes with heavy-duty, 1-piece aluminum tubing. By eliminating the OEM clip ring design at the Y-bridge in favor of a high-quality silicone boot and stainless steel T-bolt clamps, this system provides a superior seal capable of holding higher boost pressures without leaking.

The package includes a 4-inch diameter aluminum intake pipe and air box enclosure, providing a significant airflow increase over the factory diameter. A dry filter assembly with a hydrophobic Outerwears pre-filter cover is included to keep the MAF sensor and turbocharger free of contaminants. Made in the USA from 14-gauge aluminum with smooth mandrel bends, this kit is finished in a Gloss White powder coat and maintains all factory connection points and sensors for a straightforward bolt-on installation.
