Oiling System for MINI

Elevate your custom installation with the ECS -10AN O-Ring Boss fitting, a crucial component that connects your ECS Tuning Catch Can to a 3/4" ID hose. This fitting simplifies your plumbing setup, ensuring a seamless solution.

Featuring a pre-installed Viton O-ring, this fitting is engineered for excellence, providing a leak-proof seal that resists the effects of oil and fuel exposure, guaranteeing long-term durability.

The 3/4" nipple is thoughtfully designed with barbs to secure hose position effectively, minimizing the risk of hose disconnection. Keep in mind that clamps and hoses are available for separate purchase. These fittings are sold individually, with most installations requiring a pair of them.

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.

Meet modern emission regulations while preserving engine performance with the ECS Baffled Oil Catch Can. Designed for BMW and MINI vehicles, this system efficiently captures blow-by gases, preventing excessive oil vapor ingestion into the intake tract. The innovative 4-chamber baffle system maximizes oil/air separation, reducing carbon build-up and pollutants. Featuring a 1/4" drain fitting for easy maintenance, this catch can minimizes oil deposits, ensuring cleaner emissions and enhanced engine performance.

Key Benefits:

• Efficient 4-chamber baffle system for maximum oil/air separation
• Recirculated design reduces oil ingestion, promoting cleaner emissions
• Durable 6061-T6 billet machined body with anodized black finish for longevity
• Integrated dipstick and sealed reservoir for easy oil inspection and maintenance
• Serviceable design with removable baffle plates for cleaning
• Easy installation with customizable mounting options and leak-free fittings
• Engineered and manufactured in the USA for superior performance and durability

Designed to fix a known weak point for the MINI B3X and B4X engines, the ECS billet aluminium oil filter housing cap is a direct replacement for the factory plastic cap. The OEM plastic part is infamous for cracks, stripped threads, and rounded hex heads—often failing during routine oil changes and turning basic maintenance into a frustrating, time-consuming repair.

The engineers at ECS have designed a precision-machined billet aluminium upgrade that eliminates those issues, delivering strength, durability, and consistent fitment. An integrated drain plug allows you to drain the filter housing cleanly before removal, reducing spills and mess for a faster, cleaner oil service.
