Wehrli Custom Fabrication WCF100412-GRY Turbo Intake Horn - 4.8 Grey

The Wehrli Custom Fabrication WCF100412-GRY is a high-flow 4.8" turbo intake horn designed to replace the restrictive factory plastic intake horn on 2006-2010 GM 6.6L Duramax LBZ/LMM diesel engines. This precision-engineered component provides a significant increase in airflow to your turbocharger, improving throttle response and overall engine performance.

Key Features:

• CNC-machined cast aluminum construction for superior durability and heat dissipation
• 4.8" inlet diameter - the largest intake horn available for these applications
• Retains PCV connection port for proper crankcase ventilation
• Eliminates factory resonator for improved appearance and more aggressive sound
• Professional grey powder coat finish for corrosion resistance and engine bay aesthetics
• Designed to complement WCFAB Stage 1 LBZ and LMM intake kits
• Made in the USA with state-of-the-art CNC machining and powder coating

Compatibility Note: This intake horn requires a silicone boot connection. It is not compatible with OEM and aftermarket intakes that use a built-in rubber connection molded to the air intake pipe.
