Citroën 1.6THP Turbo Water Line Kit | C4 C5 DS3 DS4 DS5

Eliminate coolant leaks and safeguard your Citroën’s refined performance. The factory turbo water lines on the 1.6THP (EP6) engine are a known weak point in the cooling system. After years of extreme heat cycles, the original rigid metal pipes develop rust from the inside out, while the factory banjo eye welds succumb to vibration fatigue, leading to persistent leaks. This GryphonTek Signature Series Kit is the professional upgrade, replacing failure-prone rigid hardware with motorsport-grade Flexible PTFE Braided Stainless Steel.

• Zero-Weld PTFE Design: Replaces weak factory weld points with a continuous high-pressure PTFE core and stainless steel braid. This eliminates the risk of weld fatigue and cracking forever.
• Stop the "Disturbance Leak": Factory rigid lines often leak the moment they are disturbed during other repairs. Our flexible PTFE hoses provide the "degrees of freedom" needed for a leak-free seal every time.
• Industrial-Grade Durability: Constructed with 304 Stainless Steel braiding and anti-corrosive fittings. A rust-proof, maintenance-free solution engineered for the long-term reliability of your DS or C-series vehicle.
• Direct Citroën Fitment: 100% plug-and-play installation specifically for Citroën 1.6THP engines with factory K03 turbos. No modifications or custom bending required.
