The Wehrli WCFab Stage 1 High Flow intake bundle for 2011–2016 Duramax LML 6.6L trucks replaces restrictive factory components with larger, CNC-machined aluminum pieces to improve airflow between the turbo and engine. The kit includes one-piece high-flow intercooler pipes, a cast aluminum Y-bridge offering significantly more flow, upgraded silicone boots, and a billet resonator plate to enhance throttle response, spool-up and reliability without requiring tuning.
