MAHLE Motorsport Big End Bearing Set - N14 & N18

---

Specifically engineered for high-performance and motorsport applications, MAHLE Motorsport big end engine bearings for the Gen 2 MINI (R55–R61) equipped with the N14 and N18 turbocharged engines deliver unmatched reliability and precision under extreme conditions. Designed as a direct-fit upgrade, these bearings provide superior load capacity, wear resistance, and thermal stability compared to standard OE components.

Key Features:

• Tri-metal Construction:
  Featuring a high-strength steel backing, a lead-bronze intermediate layer, and a precision electroplated overlay, MAHLE bearings ensure optimal load distribution and fatigue resistance, crucial for high-RPM and high-boost performance.

• Enhanced Oil Retention and Flow:
  Optimised surface finish and consistent wall thickness promote improved oil film retention and hydrodynamic lubrication, reducing the risk of metal-to-metal contact even under race conditions.

• Precision Manufacturing:
  Manufactured to OE tolerances using state-of-the-art machining and quality control processes. Bearing shell alignment and crush consistency ensure a perfect fit and long-term durability.

• High Load Capacity:
  Designed to withstand increased cylinder pressures, detonation, and elevated temperatures common in tuned or track-driven N14/N18 engines.
