Subaru EJ20 EJ25 Turbo Oil Line Solutions

Professional Turbo Plumbing Solutions for Subaru EJ-Series Boxer Engines.

The Ultimate Reliability Upgrade for WRX, STI, Forester XT, and Legacy GT. Stop worrying about oil starvation and the notorious "Turbo Killer" factory filter. Our premium PTFE Braided Line Kits are engineered specifically to solve EJ-series lubrication bottlenecks. By bypassing the high-risk factory banjo bolt mesh screens, we ensure your AVCS and turbocharger receive synchronized, high-pressure oil flow. Our collection provides a service-friendly replacement for EJ205, EJ255, and EJ257 engines, designed to handle the unique harmonics of the Boxer layout.

Whether you are performing routine maintenance on a stock IHI VF-Series or Mitsubishi TD04, or building a high-boost monster with Garrett GT/GTX Series or a Rotated Turbo setup, our kits retain the same engine-side reliability upgrades—eliminating stress-cracks in rigid pipes and safeguarding your turbo investment.
