High Flow Bundle Kit Stage 1 11-16 Duramax LML Bengal Blue

The Wehrli Stage 1 High Flow Intake Bundle Kit is a premium upgrade for 2011-2016 GM 6.6L Duramax LML engines (Chevrolet Silverado/GMC Sierra 2500HD/3500HD). It improves engine performance and efficiency by enhancing airflow between the turbo and engine through smoother bends and larger diameter 14-gauge aluminum intake tubes. The kit includes a 3-inch high-flow upper intercooler pipe, a 3.5-inch passenger side intercooler pipe, and a 3-inch driver side intercooler pipe. Upgraded silicone boots and T-Bolt clamps provide increased durability and resistance to high boost pressures, preventing leaks. A threaded bung is included for the OEM intake temperature sensor. This kit is designed for straightforward installation on stock trucks, requiring no additional upgrades, modifications, or tuning, and aims to deliver improved throttle response, quicker turbo spool-up times, and a more aggressive turbo sound.
