Take Back Your Duramax's Power

Unlock your Duramax's full potential with Wehrli's Stage 2 High Flow Intake Bundle Kit. Designed specifically for the 2017-2019 L5P Duramax, this upgrade combines our Stage 1 High Flow Bundle and Stage 2 Intake Kit into one convenient yet powerful package. The result? Improved efficiency, quicker throttle response, and faster turbo spool-up, thanks to the optimized airflow to the engine and turbo. This kit is designed to eliminate common weak points in the factory's design that contributes to lost power, boost leaks, and even complete failures, especially in demanding, heavy-duty applications. Wehrli's Stage 2 kit replaces the weak, restrictive OEM components with a high-flow fabricated intake pipe, intake horn, and airbox enclosure with a dry filter assembly. These upgraded parts significantly increase airflow to your Duramax's engine and turbo, and as a result, this system improves horsepower, torque, and lowers intake temperatures by drawing in cold air through your hood's air duct and inner fender. With this Stage 2 intake bundle, your L5P Duramax will breathe easier, perform better, and deliver the power and efficiency you need to tackle any challenge.

Designed to Last

Stage 2 High Flow Intake Bundle Kit from Wehrli is built for performance for the long haul. Crafted from high-strength 14-gauge aluminum, this system features large 4-inch diameter piping with smooth, aerodynamic bends, and the intake horn is also over an inch larger in diameter than its OEM counterpart, resulting in superior intake air velocity and volume. When paired with a Max Effort Tune and Wehrli's 3.5-inch turbo inlet, you could experience up to a 25HP gain. Furthermore, ease of installation is at the forefront of this kit's design. This system uses high-quality hardware, silicone boots, seals, and stainless steel t-bolt clamps. It also includes a hydrophobic pre-filter cover and a removable air box lid that allows for quick visual inspection and maintenance of your WCFab filter, keeping your 6.6L Duramax protected from any contaminants. The full assembly is then finished in your choice of WCFab's signature custom powder coat colors, giving your GM truck a unique look that stands out. Installation is remarkably straightforward, using only basic hand tools. No tuning is required. Plus, you'll save roughly $60 versus buying the components separately.
