Wehrli Custom Fabrication WCF100417-DG High Flow Turbo Intake Horn Dark Gray

The Wehrli Custom Fabrication WCF100417-DG is a high-flow cast aluminum turbo intake horn finished in a Dark Gray powder coat. Designed as a direct replacement for the restrictive OEM plastic inlet, this precision-engineered component delivers measurably improved airflow to the turbocharger for enhanced throttle response and performance.

Key Features:

• 4.8-inch inlet — the largest intake horn available for this application
• CNC machined cast aluminum construction for maximum durability and precision
• 5.6% improvement in airflow over the stock intake horn
• Integrated PCV port connection for proper crankcase ventilation routing
• Eliminates the factory resonator for a cleaner engine bay and more aggressive turbo sound
• Includes stainless steel T-bolt clamps and silicone reducer boot
• Includes O-ring seal and new EGR gaskets
• Custom Dark Gray powder coat finish
• Made in the USA

The WCF100417-DG must be used with an intake pipe that accepts a 4-inch boot-and-clamp connection. It is not compatible with OEM or aftermarket intakes that use a molded rubber connection directly onto the horn. This intake horn is designed to complement Wehrli's Stage 1 LML Intake Kits and Stage 1 High Flow Bundle Kits.

Important: 2011 model year trucks must update the PCV Regulating Valve to 2012–2016 specification for correct fitment. Not compatible with aftermarket LML Y-bridges that relocate the manifold inlet from the factory driver-side location. This product cannot ship to the state of California.
