Technical Description
Eliminate the "Hidden Assassin" in your oiling system. The factory engine block oil feed on Subaru EJ20 and EJ25 engines features a banjo bolt with a built-in mesh screen. While designed to catch debris, this screen eventually clogs with carbonized oil, leading to instantaneous turbocharger seizure—earning it the name "The Turbo Killer." This GryphonTek Signature Series Fitting is the mandatory foundation for any reliability upgrade, replacing the factory bottleneck with a high-flow -4AN Flare and a filter-free oil path.

- "Turbo Killer" Filter Delete: Specifically engineered to replace the factory filtered banjo bolt. By removing the internal mesh screen, you ensure a constant, unrestricted oil supply to your turbocharger even under high-load conditions.
- DIY Braided Line Foundation: The essential starting point for any enthusiast upgrading to -4AN braided PTFE oil lines. This fitting bridges the gap between the EJ engine block's oil gallery and high-performance motorsport plumbing.
- Industrial-Grade Resilience: Machined from high-tensile mild steel and electroplated for maximum corrosion resistance against the intense radiant heat of the Subaru engine bay.
- Zero-Leak Sealing: Includes high-purity annealed copper crush washers, ensuring a professional, high-pressure seal that survives the extreme thermal expansion of the EJ block.
