Technical Description

Establish a high-volume, unrestricted return path for your EFR build. The BorgWarner EFR 6258 and 6758 move significant oil volume through their bearing cartridges. To prevent back-pressure and seal failure, an efficient drainage path to the oil pan is critical. This GryphonTek Signature Series Kit provides the specific EFR-pattern hardware and high-temp plumbing needed to bridge the gap in one coordinated package.

  • EFR Specific Geometry: CNC-machined 6061-T6 billet aluminum flange with precise EFR bolt spacing ensures a perfectly flat, leak-free interface.
  • Maximum Evacuation Path: Optimized internal diameter prevents the back-pressure that causes oil to blow past EFR seals into the exhaust.
  • Industrial NBR Construction: Multi-layer reinforced oil-resistant hose remains flexible under extreme thermal cycles and absorbs high-frequency B6/BP harmonics.
  • Zero-Leak Interface: Includes premium Interface N-8092 non-asbestos gaskets and high-torque clamps for long-term sealing integrity.
