Eliminate the Weak Points of Stock Design

It's no secret that your high-performance Duramax loves to breathe tons of fresh, cool air. However, the stock intake often falls short of your engine's needs. Fortunately, Wehrli provides the perfect solution with the Stage 3 High Flow Intake Bundle Kit for the 2017-2019 L5P 6.6L Duramax. This kit combines our Stage 2 High Flow Bundle and 3.5 in. Down Pipe into a single package, providing increased air and exhaust flow for your turbo and engine for improved efficiency, throttle response, and turbo spool up. By addressing key restrictions in the factory design, this upgrade helps eliminate weak points that can contribute to lost power, boost leaks, and potential failures during heavy-duty applications. The cold air intake in this kit replaces the restrictive stock components with high-performance, fabricated parts designed for maximum airflow. The high-flow intake pipe, upgraded intake horn, and air box enclosure with a dry filter assembly work together to provide smoother, uninterrupted air delivery to the engine. Get the most out of your 6.6L Duramax with this Stage 3 Intake Bundle Kit from Wehrli.

All Aluminum Construction

The WCFab Performance Intake System is built with all-aluminum 14 gauge construction, providing both durability and lightweight strength. The system features large-diameter 4-inch piping with smooth, aerodynamic bends. This design results in improved throttle response, increased power output, and a more aggressive engine and turbo sound that is sure to turn heads. The intake horn included in this system is over an inch larger in diameter compared to its OEM counterpart, further optimizing airflow into the turbocharger. This kit also features a removable air box lid, allowing for easy visual inspection and maintenance of your WCFab filter. To ensure long-lasting performance, the system comes equipped with high-quality hardware, including silicone boots, seals, and stainless steel T-bolt clamps, which ensure a secure, leak-free installation while providing durability even under extreme conditions.
