Component Breakdown
Engineering features explained
Heat-Resistant Composite Cover
Injection-moulded composite or aluminium alloy housing withstands continuous exposure to engine heat cycles without warping. Designed for exact OEM tolerances to maintain a secure seal across the cylinder head.
Integrated Bolt Seat Design
Reinforced bolt seats distribute load evenly during tightening, preventing warping or cracking. Ensures consistent clamping pressure across all gasket contact points.
High-Integrity Gasket Channel
Precision-machined channel retains gasket alignment and ensures uniform compression during installation. Tested for oil retention and resistance to blow-by under high crankcase pressure.
Oil Baffle & Drain Pathway
Internal oil flow guides reduce pooling and direct return oil efficiently back to the sump. Designed to minimise oil aeration and maintain proper lubrication balance under high RPM.
Chemical & Thermal Barrier Coating
Protective coating resists corrosion, oil degradation, and thermal fatigue. Extends component lifespan and maintains sealing performance even under repeated thermal expansion.
