Technical Description

The total reliability solution to eliminate "Burning Oil" risks and cabin odors. The Citroën 1.6THP (EP6) engine operates in an extremely high-temperature environment that inevitably destroys factory plumbing. The rigid oil feed (OE #037956) fails at its O-ring and crimp points, while the rubber drain hose (OE #037979) hardens and seeps oil. This GryphonTek Signature Series Complete Kit is the professional upgrade—replacing failure-prone OEM hardware with motorsport-grade PTFE Braided Stainless Steel and High-Temp Silicone.

  • Double Leak Protection: Replaces both the high-pressure feed and the high-flow return circuit. Our flexible designs eliminate the "rotation leak" phenomenon at both factory crimps and rubber junctions.
  • Precision Pressure & Flow: Features a 1.8mm restricted banjo bolt for the turbo side to protect internal seals, paired with a billet aluminum high-flow return fitting for unrestricted drainage.
  • Industrial-Grade Thermal Defense: Includes a high-temp PTFE core and reinforced silicone protected by an Aluminum Foil Corrugated Sleeve to survive intense radiant heat.
  • Direct Citroën Fitment: A 100% plug-and-play refresh for C4, C5, DS3, DS4, and DS5 models. Designed to navigate the specific EP6 engine bay geometry perfectly.
