Manufactured from 6086-T6 aerospace grade aluminium, Koflach Engine Developments’ N54 crank bolt capture plates are designed to eradicate the all-too common loosening of the crank hub bolt on BMW’s N54 engines. Designed and machined right here in Sussex, UK, and supplied with 12.9 grade fitting hardware. The capture plates also undergo a ‘hard-anodising’ process, producing a far tougher surface coating than traditional aluminium anodising, ensuring the plates looks good and performs for the life of the vehicle.
