Wehrli Custom Fabrication WCF100412-BB High Flow Turbo Intake Horn Bengal Blue 2006-2010 Duramax LBZ/LMM

The Wehrli Custom Fabrication WCF100412 High Flow Cast Aluminum intake horn replaces the restrictive OEM plastic inlet to provide increased airflow to your turbo for improved performance and throttle response on 2006-2010 GM 6.6L Duramax LBZ/LMM engines. This unit comes with a custom single-stage powder coating in a striking Bengal Blue finish to enhance your engine bay appearance.

Key Features:

• 20% improvement in air flow versus stock
• 4.8 inch inlet, largest intake horn on the market
• CNC machined cast aluminum construction
• Includes PCV port
• Eliminates resonator connection for improved appearance and more aggressive sound
• Includes silicone reducer boot and stainless steel T-bolt clamps
• O-ring seal for secure fitment
• Made in USA

The improved airflow path helps increase turbo efficiency, improve throttle response, and support higher horsepower builds while maintaining reliable daily driving performance. This intake horn is designed to complement the WCFAB Stage 1 LBZ and LMM intake kits.

Important Compatibility Note: Not compatible with OEM and aftermarket intakes that do not use a silicone boot connection at the horn. If your intake has a built-in rubber connection that slides onto the OEM horn and is molded to the air intake pipe, it will not fit with this horn. If your intake uses a boot and two clamps for connection, this horn will work with that intake.
