Keep your Nissan D22 YD25DDTI turbo-diesel engine running cool, clean, and leak-free with this Gryphontek Turbo Oil & Water Line Kit, engineered as a direct-fit replacement for the factory oil and coolant lines used with the RHF4 VN4 turbocharger.

On older D22 and NP300 vehicles, the OEM steel oil feed pipe, rubber drain hose, and rigid coolant lines often suffer from cracking, rust, and internal blockage after years of exposure to heat and vibration—leading to oil starvation, coolant leakage, overheating, and shortened turbo lifespan.

This upgraded kit replaces every critical turbo line with flexible, heat-resistant, and corrosion-proof components designed specifically for diesel reliability.

The 4AN PTFE stainless-braided oil feed line ensures stable oil pressure to the turbo; the high-temp silicone oil drain hose maintains smooth drainage into the sump; and the 4AN braided stainless water lines deliver consistent coolant flow to keep the CHRA properly cooled.

Ideal for turbo rebuilds, replacements, or preventive maintenance, this kit provides OEM-style fitment with a major improvement in durability and long-term performance.
