Wossner S2000 F20C High Compression Forged Piston Kit Hard Anodised The Wossner S2000 F20C High Compression Hard Anodised Piston Kit is the ultimate internal upgrade for elite naturally aspirated (NA) builds. Engineered for the high-revving 2.0L VTEC engine, these pistons increase the compression ratio to a potent 12.5:1, significantly enhancing thermal efficiency and power output. This specific "Premium Plus" series features a professional Hard Anodised crown coating, providing a ceramic-like thermal barrier that protects the piston against the extreme cylinder temperatures and pressures associated with high-RPM competition use. Manufactured in Germany from high-silicon 4032-T6 forged aluminium, these pistons offer a superior strength-to-weight ratio while maintaining low thermal expansion. The Hard Anodising process doesn't just protect the crown; it toughens the ring grooves to prevent micro-welding—a common failure point in high-stress racing engines where the ring fuses to the piston. Combined with Wossner’s signature Moly skirt coating for reduced friction and mirror-polished crowns for better heat distribution, this kit is designed for builders who refuse to compromise on longevity or performance. Key Performance Features Extreme 12.5:1 Compression: Maximises naturally aspirated power and torque by increasing the engine's static compression ratio. Hard Anodised Crown Coating: Provides a high-tech thermal barrier that withstands intense heat and protects against surface erosion. Anti-Micro-Welding Protection: The anodised ring lands prevent ring-to-groove fusion, ensuring a perfect seal under extreme stress. Low-Expansion 4032-T6 Alloy: Allows for tighter, quieter piston-to-bore clearances and exceptional fatigue resistance. Moly-Coated Skirts: Reduces parasitic drag and internal wear, ensuring smoother operation through the entire 9,000+ RPM range.
