Turbo Lines & Hoses

The turbocharger oil supply line is one of the most common failure points on N14 and N18-equipped R5X MINIs. Responsible for delivering a steady stream of pressurized oil to the turbocharger’s center housing (CHRA), this line keeps the turbo’s bearings properly cooled and lubricated. Unfortunately, its location directly alongside the exhaust manifold and catalytic converter exposes it to extreme heat. Over time, this heat causes the oil inside the line to harden or “coke,” creating a permanent restriction that starves the turbo of vital lubrication.

MINI attempted to address this issue by adding a retrofit heat shield to N14 models, but the problem continues to plague MINI owners. Furthermore, the OEM banjo bolts rely on copper crush washers that become brittle and warp under heat, leading to persistent oil leaks at the back of the engine.

To eliminate these issues, ECS developed a high-performance replacement for the factory turbocharger oil feed line (11657534454). Built from premium stainless steel braided -4 AN hose and engineered to withstand the harsh thermal environment of the N14/N18 engine bay, this upgrade ensures consistent, dependable oil delivery. A PTFE inner lining provides exceptional chemical and temperature resistance, while black zinc–coated fittings and banjo bolts offer improved corrosion protection and long-term sealing. The result is a durable, leak-free solution that outperforms the factory design in every way.

Features:

-4 AN stainless steel braided hose eliminates the OE swivel fittings for superior sealing and consistent oil flow

PTFE inner lining delivers outstanding chemical and temperature resistance

Black-anodized aluminum AN fittings offer improved durability and a refined appearance

Black zinc–coated banjo bolts resist corrosion for a long-lasting repair

Includes four new crush washers to ensure proper sealing during installation

Whether you're fixing an oil leak or performing preventative maintenance, choose the ECS upgraded turbocharger oil feed line for lasting durability and leak-proof performance.
