MINI Cabrio R57 LCI Coop.S JCW 2010-2015 N14B16A 5FX 5FY 5FT 5FR 5FV 5F04 5F02 Aluminum N14B16A 5FX 5FY 5FT 5FR 5FV 5F04 5F02 Cylinder Head for Citroen Peugeot Cooper EP6 – OEM 11127577371

Product Overview: This complete cylinder head assembly is manufactured for the 1.6-litre turbocharged direct-injection Prince engine family, shared between MINI, BMW and PSA applications and identified by engine codes N14B16A and the related 5FX, 5FY, 5FT, 5FR, 5FV, 5F04 and 5F02 designations. It is supplied fully assembled with valves, guides and seats installed and machined to original equipment tolerances, providing a reliable replacement for a warped, cracked or valve-damaged original cylinder head.

Key Features: The casting is produced from high-grade aluminium alloy and CNC-machined for accurate deck flatness, correct valve seat concentricity and consistent combustion chamber volume. Valve guides and seats are pre-installed and honed for even sealing and balanced compression, and the combustion chambers are sized to maintain the compression ratio required by the turbocharged configuration. Cam carrier surfaces are finished for correct bearing clearance, and intake and exhaust flanges ensure reliable gasket sealing.

Vehicle Compatibility: This head fits MINI Cabrio R57 LCI Cooper S JCW (2010-2015), MINI R56 Cooper S JCW (2007-2010), MINI Cabrio R57 Cooper S (2007-2010), MINI Clubman R55 LCI Cooper S JCW (2010-2014), MINI Clubman R55 Cooper S (2006-2010) and MINI Paceman R61 (2012-2016), plus related BMW 1 Series and PSA applications using this engine family. Confirm the engine code and OE reference before ordering.

Applications: Suitable for compact performance hatchbacks, convertibles and small crossovers, covering everyday repairs, turbocharger-related engine work, workshop overhauls, rebuilds and fleet maintenance requiring a factory-specification head.

Benefits / Replacement Information: Fitting this assembly restores compression, corrects coolant and combustion gas leakage caused by cracking or distortion, and removes the expense of separately reconditioning valves, guides and seats. A complete unit reduces downtime and simplifies the repair.

Installation or Fitment Notes: Installation must be performed by a qualified technician. Clean and verify block deck flatness, fit a new head gasket and new head bolts as specified, and torque in the correct sequence and angular stages. Replace timing chain components and coolant during the job, verify valve clearances and direct-injection injector sealing, then run the engine and check for leaks before road testing.
