Exhaust Manifold to Head Bolts - MINI Gen 1

Ensure a secure and reliable seal between your manifold and cylinder head with this high-quality Manifold to Head Bolt Kit, suitable for MINI R50 One and Cooper, MINI R52 Cooper and Cooper S (Convertible), and MINI R53 Cooper S and GP models. Designed as a direct replacement for the original hardware, these bolts feature the correct thread pitch and length to provide a precise fit and dependable clamping force under high temperatures. Exhaust manifold bolts are constantly exposed to extreme heat cycles, which can cause corrosion, fatigue and seizure over time, often leading to snapped bolts or exhaust leaks — particularly on supercharged R53 Cooper S and GP models. Replacing them during a manifold upgrade, supercharger modification, cylinder head replacement or full engine rebuild ensures proper torque retention and long-term reliability. Ideal for both standard and performance manifolds, this kit helps you complete the installation correctly the first time, without risking the reuse of worn or heat-stressed hardware.
