Wehrli Custom Fabrication WCF100674 T3/T4/T6 Turbocharger -10AN Extended Oil Drain Fitting Kit

The Wehrli Custom Fabrication WCF100674 is a precision-engineered extended oil drain fitting kit designed to improve turbocharger oil drainage and simplify installation on T3, T4, and T6 small and midframe turbochargers. This CNC-machined billet aluminum fitting extends the oil drain connection point 4 inches away from the turbo center section, providing significantly better wrench access and making routing the drain line much easier during installation.

Key Features:

• CNC-machined billet aluminum construction with black anodized finish
• Extended -10AN male fitting positioned 4 inches from turbo drain flange
• Reusable O-ring seal eliminates common paper gasket leaks
• Compatible with T3/T4/T6 small and midframe turbochargers using 2-inch on-center bolt spacing
• Lowers drain line connection point for improved accessibility
• Made in the USA

This extended oil drain fitting kit is ideal for custom turbo installations, high-performance diesel builds, and racing applications where reliability and ease of maintenance are essential. The reusable O-ring sealing system allows for repeated removal and reinstallation without replacing gaskets, making it a superior alternative to traditional paper gasket drain flanges. Commonly used on Cummins, Duramax, and Power Stroke diesel performance builds.
