This kit also replaces the restrictive OEM components of your air intake with a more reliable a high-flow fabricated intake pipe, intake horn, and airbox enclosure with a dry filter assembly. The result is improved performance and a more aggressive sound that is sure to turn heads, thanks to the steady supply of cold air hitting the Duramax engine. Whether you're pushing your Duramax to its limits or simply want to enjoy a more dynamic driving experience, Wehrli's Stage 2 High Flow Intake Bundle ensures your engine performs at its best while turning heads at every corner. Increased Durability with Alumium Construction The all-aluminum construction of the Stage 2 Intake Bundle features 14-gauge material and large 4-inch piping with smooth, aerodynamic bends. The intake horn is over an inch larger in diameter than its factory counterpart, contributing to better turbo performance, higher horsepower and torque, and cooler intake temperatures. The included high-quality hardware, including silicone boots, seals, and stainless steel t-bolt clamps, ensures maximum durability and easy installation. Furthermore, maintance is a breeze with the removable airbox lid element, which allows for easy visual inspection of your WCFab filter with included hydrophobic pre-filter cover. The Stage 2 kit replaces the OEM 2-piece 2.5-inch driver (hot) side intercooler pipe and the leak-prone 2-piece plastic/rubber passenger (cold) side pipe with WCFab's heavy-duty, 1-piece intercooler pipes. The 3-inch driver-side pipe eliminates the OEM middle boot joint, improving flow and durability, while the 3.5-inch passenger-side pipe features a CNC-machined flange with a double O-ring seal, an upgraded silicone boot, and reinforced components to handle higher boost pressures. The full assembly is then finished in your choice of WCFab's signature custom powder coat colors, giving your engine bay a look as unique as your GM truck. The kit installs with basic hand tools and no tuning is required. Plus, you'll save about $64, compared to purchasing the components individually.
