The RAD Valve Block Cage Kit features carbon fibre reed petals and advanced aerodynamic design for improved engine performance. It enhances airflow, increases horsepower, and reduces reed petal wear with a screw-free design for simplified maintenance and quick reed petal replacement. Key features include reduced reed petal travel for greater efficiency, a screw-free design to prevent screw ingestion, a new reed petal resin system with custom carbon fibre lay-up, pre-curved reed petals for better sealing, a wider reed cage for maximum airflow, and an increased combined reed tip area for greater total airflow. The airfoil shape on the cage tip increases air velocity, while long reed stops progressively slow petal tip velocity for enhanced durability. The central wing has a reduced frontal area and a more aerodynamic profile. Manufactured using high-tech materials for consistent reliability, it meets or exceeds OEM specifications and is a direct OEM replacement. Cross-reference OEM part numbers include Force3 V382S-A, 4ES-13610-00-00, 4ES-13613-00-00, and 95022-06020-00. Visual inspection of the product image is recommended before ordering. Easy to install, professional installation is suggested if uncertain.

FULL DESCRIPTION

RAD Valve Block Cage Kit - Carbon Fibre

Enhance your engine's performance with the RAD Valve Block Cage Kit. This high-performance upgrade is engineered to improve airflow, boost horsepower, and significantly reduce reed petal wear for extended engine life.

Featuring advanced carbon fibre reed petals and a sophisticated aerodynamic cage design, this kit ensures efficient engine operation and simplifies maintenance with its innovative screw-free construction.

Key Features:

  • Improved Efficiency: Reduced reed petal travel optimizes performance.
  • Increased Horsepower: Enhanced airflow directly translates to more power.
  • Extended Durability: Carbon fibre reed petals resist wear, prolonging service life.
  • Screw-Free Design: Eliminates the risk of screw ingestion into the engine and allows for rapid reed petal replacement.
  • Advanced Reed Technology: Utilizes a new reed petal resin system with a custom carbon fibre lay-up for superior performance.
  • Optimized Sealing: Pre-curved reed petals ensure a better seal at the tip.
  • Maximum Airflow: A wider reed cage design maximizes air intake.
  • Increased Reed Tip Area: A 10.5% increase in the combined reed tip area allows for greater overall airflow.
  • Enhanced Air Velocity: The airfoil shape on the cage tip boosts air velocity from the outer ports.
  • Progressive Petal Slowdown: Long reed stops gradually reduce reed petal tip velocity, enhancing durability.
  • Aerodynamic Cage: A 15.6% reduction in the frontal area of the central wing, combined with a more aerodynamic profile, improves efficiency.
  • High-Tech Materials: Manufactured using advanced materials for consistent and reliable performance.
  • OEM Specifications: Meets or exceeds original equipment manufacturer standards.
  • Direct Replacement: Designed as a direct fit for easy installation.

Cross-Reference OEM Part Numbers:

  • Force3 V382S-A
  • 4ES-13610-00-00
  • 4ES-13613-00-00
  • 95022-06020-00
