Wehrli Custom Fabrication WCF100417-BR High Flow Turbo Intake Horn Bengal - 5in Red

The Wehrli Custom Fabrication WCF100417-BR is a high-performance turbo intake horn designed to replace the restrictive factory plastic inlet on 2011-2016 LML Duramax engines. This CNC-machined cast aluminum intake horn features a massive 4.8-inch inlet—the largest on the market—delivering increased airflow to the turbocharger for improved performance and throttle response.

Key Features:

• 4.8-inch inlet diameter for maximum airflow capacity
• CNC-machined cast aluminum construction for durability and precision fitment
• Integrated PCV port for proper crankcase ventilation
• Eliminates restrictive factory resonator connection
• Bengal Red powder coat finish for custom appearance and corrosion resistance
• Includes silicone reducer boot and stainless steel T-bolt clamps for secure installation

This direct-fit upgrade is manufactured in the USA by Wehrli Custom Fabrication using state-of-the-art CNC equipment to ensure precise tolerances and quality construction. The intake horn works with most aftermarket intake systems that use a removable boot connection with clamps. Note: Not compatible with aftermarket LML Y-bridges that relocate the inlet from the factory driver-side position. 2011 model year trucks require PCV regulating valve update to 2012-2016 specification for proper fitment.
