Wossner Accord & CR-V K24 9.0:1 Compression Forged Piston Kit Hard Anodised The Wossner K24 Hard Anodised Low Compression Piston Kit is the ultimate internal foundation for high-displacement Honda turbo builds. Specifically designed for the K24A series engines, this "Premium Plus" kit reduces the static compression ratio to 9.0:1, providing the critical safety margin required for high-boost applications. By lowering the compression, tuners can push significantly more boost through the 2.4L block, unlocking massive torque and horsepower figures while maintaining stability against engine-damaging detonation. Engineered in Germany, these pistons feature a professional Hard Anodised crown coating that acts as a sophisticated thermal barrier. This ceramic-like shield reflects extreme combustion heat away from the piston substrate, preventing surface erosion and thermal distress during prolonged high-load sessions. Additionally, the anodised ring lands are specifically toughened to prevent "micro-welding"—a failure mode where the piston ring fuses to the groove—ensuring a perfect ring seal and long-term reliability for elite street and track projects. Key Performance Features Turbo-Optimised 9.0:1 Compression: Specially designed to handle the increased cylinder pressures and thermal loads of forced induction. Hard Anodised Crown Coating: Provides a high-tech thermal shield that increases piston longevity and protects against surface melting. Anti-Micro-Welding Protection: Anodised ring grooves ensure the rings remain free and functional under extreme thermal stress. 4032-T6 High-Silicon Alloy: Offers maximum structural integrity with low thermal expansion for tighter, quieter engine clearances. Moly-Coated Skirts: Signature permanent dry-film lubricant reduces parasitic drag and protects cylinder walls from scuffing.
