Wehrli Custom Fabrication -10AN Extended Turbo Oil Drain Fitting Kit (Black Anodized) – T3/T4/T6 Midframe Turbos
The Wehrli Custom Fabrication -10AN Extended Turbo Oil Drain Fitting Kit is a precision-machined solution designed to simplify turbo oil drain line installation and maintenance. This billet aluminum adapter flange features a 4-inch extended -10AN male fitting that lowers the threaded connection point away from the tight confines of the turbo center section, making it much easier to reach with a wrench. The kit includes a reusable O-ring seal that eliminates the common issues of leaking or torn paper gaskets at the turbo drain port. It is compatible with T3, T4, and T6 midframe turbochargers that use standard 2-inch on-center bolt spacing. CNC-machined from billet aluminum and finished in durable black anodizing, this fitting kit provides a clean, professional installation while improving serviceability and reliability in high-performance turbo setups.

Turbo Install Kits
Turbo install kits provide the oil feed and drain lines, coolant supply and return lines, mounting hardware, gaskets, and fittings needed to complete a turbocharger installation without sourcing individual components separately. Using a purpose-built install kit ensures correct oil supply restriction, proper drain slope, and leak-free connections at every turbocharger port. What Is Included in a Turbo Install Kit A complete turbo install kit typically includes a stainless steel braided oil feed line with an inline restrictor fitting sized for the turbocharger's journal or ball bearing type, a larger-diameter oil drain line with a heat-resistant silicone section, coolant supply and return lines for water-cooled turbochargers, a set of V-band or flange gaskets for the turbine inlet and outlet, and any required O-rings or copper crush washers for the turbocharger oil ports. Some kits include a pre-lubrication tool for filling the center housing before first startup. Why is the oil feed...
