- The 5% reduction in combustion chamber volume provides a high compression ratio, resulting in better thrust and improved combustion efficiency.
- Icreased power throughout the rev range (especially bottom/mid), improved fuel economy and greatly reduced risk of detonation.
- The combustion chamber insert is machined much thinner, increase the coolant volume and shorten the distance through which heat passes.
- The heat sinks increase 30% heat dissipation area and effectively prevent the engine from overheating
- The split design is more conducive to coolant flow, and achieve better cooling effect in a short time.
- Dynamic anodized surface for added corrosion resistance. Also make you stand out from the crowd.
- Machined by the latest generation CNC technology that ensures high accuracy for a perfect fit.
- Made from light 6061-T6 billet aluminum with superior strength and rigidity.
