Product Description

The Torque Solution TS-SU-486K-S -10AN Turbo Oil Return Line Kit is engineered specifically for the Subaru EJ engine family, and is tailored for setups that use rotated or aftermarket turbos where the stock oil return line may be insufficient. It provides a proper, kink-free, correctly sized oil return path for optimal turbo operation and longevity. By replacing the OEM return tube with a bespoke head fitting and stainless braided hose, this kit is ideal for high-performance or modified applications requiring reliable oil drainage from the turbo.

Installation is straightforward for competent fabricators or performance technicians: remove the factory return tube on the cylinder head, bolt in the supplied head fitting with high-temp O-rings, route the braided hose to the supplied flange, and mount the flange to the turbo drain point. Because the hose is supplied at roughly 9 inches and must be trimmed to fit, routing can be optimized for clearance and aesthetics. This kit is designed for Subaru EJ-series engines of all years (EJ20, EJ25) but is especially suited for aftermarket turbo installations in WRX, STi, Impreza, Legacy and other EJ-based platforms. Always verify your specific engine code and turbo drain configuration before installation.

Note: Whilst the manufacturer states "EJ All Years", you should confirm your specific engine code, drain flange style, and turbo orientation match the kit. The suffix "-S" designates the "stock-location turbo" variant of the kit. If your turbo is rotated or uses a significantly non-standard drain arrangement, verify that the kit's hose length, flange, and port align with your setup.
