The Wehrli Custom Fab High Flow Intake Bundle Kit (Stage 3) in Illusion Purple (MPN: WCF100403-IP) is designed for 2017-2019 Chevrolet Silverado/Sierra 2500/3500 HD models equipped with the L5P Duramax diesel engine. This comprehensive kit includes a 4-inch turbo inlet, intercooler piping (3-inch driver side, 3.5-inch passenger side), and a high-flow air filter with a hydrophobic pre-filter cover, all constructed from heavy-duty 14 gauge aluminum for enhanced durability and optimized airflow. The kit is designed to improve performance, with claimed gains of 25 horsepower when used with a Max Effort Tune. It features high-quality hardware, silicone boots, seals, and stainless steel t-bolt clamps for a secure and easy installation. The removable air box lid allows for convenient filter inspection and maintenance, and the ram air duct seal is relocated for a cleaner engine bay appearance. This kit aims to reduce restriction and improve efficiency over the OEM components.
