Product Details

The Wehrli Custom Fabrication WCF100412-FTB Billet Intake Horn is a precision-machined, high-flow replacement intake horn designed to improve turbocharger inlet efficiency on GM Duramax diesel engines. Manufactured from aircraft-grade billet aluminum, this intake horn replaces the restrictive factory plastic unit to deliver improved airflow, greater durability, and a polished under-hood appearance.

Wehrli Custom Fabrication engineers each intake horn to maximize the cross-sectional area through the turbo inlet path, reducing intake restriction and helping support higher horsepower builds. The FTB designation indicates this piece is finished in Wehrli's signature Illusion Faded Teal/Blue (FTB) color, a custom anodized finish that delivers a distinctive, show-quality look.

Key Features:

  • Precision CNC-machined from billet aluminum for superior strength and longevity
  • Direct OEM replacement — bolt-on installation, no cutting or welding required
  • High-flow design reduces intake restriction compared to the factory plastic horn
  • Illusion Faded Teal/Blue (FTB) custom anodized finish for a premium appearance
  • Compatible with stock and upgraded turbocharger setups
  • Manufactured in the USA by Wehrli Custom Fabrication

Whether you're building a dedicated performance diesel or simply want a more durable and better-flowing intake solution, the Wehrli Custom Fabrication WCF100412-FTB Billet Intake Horn is a direct upgrade over the factory unit and a hallmark of WCF's commitment to quality American craftsmanship.

Everything went very well and quickly.

Por ahora todo bien

Pricing was better than other business and I prefer to do business with local companies

I never received anything about shipping so I contacted customer support. They said it was a direct shipment and they would check on it for me and get back to me. I never heard back from them. Shortly after that I did receive a message from the carrier saying they have my shipment and scheduled a delivery. They said they would call me 30 mins before the delivery so I could get off work and come to inspect it before signing for it. That didnt' happen either my wife called me first thing in the morning and say they are here delivering it now so I had to run home so I could inspect it. The driver was really nice and waited for me to get there.
