Moroso 23720 Turbo Oil Return Fitting for Mitsubishi EVO - 8AN 7/8/9

The Moroso 23720 is a precision-engineered -8AN turbo oil return line fitting designed specifically for use with the Moroso 20967 aluminum oil pan on Mitsubishi Lancer Evolution 7, 8, and 9 models equipped with the 4G63 turbocharged engine. This fitting provides a secure, leak-free connection for turbocharger oil drain-back applications, making it essential for turbocharged performance builds and upgraded turbo installations.

Key Features:

• -8AN male fitting accepts standard -8 braided stainless hose or PTFE hose assemblies
• Engineered for Moroso part number 20967 oil pan with 1.5-inch bolt hole center-to-center spacing
• Compatible with larger aftermarket turbochargers requiring increased oil return capacity
• Also fits other custom applications with matching 1.5-inch mounting pattern
• Aluminum construction for lightweight durability and heat resistance
• Provides proper oil drain angle to prevent turbo oil starvation and bearing failure

This fitting is particularly valuable for performance enthusiasts running upgraded turbochargers on Mitsubishi EVO platforms, where increased oil return flow is critical for turbo longevity. The -8AN size provides superior flow capacity compared to stock oil return systems, helping to prevent oil backup in the turbo center housing that can lead to seal failure and excessive smoke.
