Wehrli WCFab Intake Horn for 2011–2016 6.6L Duramax LML swaps the OEM plastic inlet for a cast-aluminum high-flow horn to increase turbo airflow and improve throttle response. With a large 4.8–5.0 inch inlet, PCV port, silicone reducer boot and stainless T-bolt clamps, it eliminates the resonator for a cleaner look and more aggressive induction sound. Powder coated WCFab red, it complements Wehrli Stage 1 kits and replaces GM part numbers 12642296 and 12637801.
