ANDO RACING AN10 Oil Drain Flange – Funnel Oil Return for T3/T4 GT Turbos

Overview

The ANDO RACING AN10 Oil Drain Flange is a precision-crafted funnel-type oil return adapter designed to manage turbo oil flow with clarity and reliability. Forged from CNC-machined T-6061 aluminum, it emphasizes a sturdy build that resists warping and keeps leaks at bay, even under spirited driving or daily usage. The result is a clean, dependable connection that complements a turbocharged engine bay without adding complexity.

With its funnel-shaped oil inlet, this flange promotes a smooth, continuous flow and a consistent oil supply to the turbocharger, helping to reduce irregularities in return flow. The combination of a streamlined exterior and a robust internal path translates to a tidy installation and a confident seal against leaks, so you can focus on performance rather than maintenance.
