The Skunk2 Pro Series Honda/Acura B-Series VTEC XP Valve Spring Set is engineered for high-performance racing applications. Designed specifically for turbocharged and high-RPM engines, these springs feature a seat pressure of 93 lbs at 1.320 inches and an open pressure of 238 lbs at 0.820 inches, ensuring optimal valvetrain stability even beyond 11,000 rpm. Crafted from super-clean chrome-silicone wire milled in Japan, each spring undergoes rigorous manufacturing processes including heat treatment, shot-peening, chemical polishing, and nitriding to maximize strength, durability, and resistance to load loss. These features make the springs ideal for use with high-lift camshafts and in extreme engine conditions, providing reliable valve control during prolonged high-RPM operation. The dual-spring design, with inner and outer springs fit together with a slight interference fit, prevents valve float and maintains consistent pressure at extreme engine speeds. Each set contains 16 springs, meticulously manufactured and inspected to meet championship-level racing standards. Whether installed on Honda Civics from 1994 to 2000 or Acura Integras from 1998 to 2001, these springs deliver superior performance, durability, and stability for demanding motorsport environments. Skunk2’s dedication to quality ensures these springs are robust enough for extreme racing conditions, making them a top choice for professional engine builders and enthusiasts seeking maximum power and reliability at high RPMs. Engineered with precision and tested extensively, the Skunk2 Pro Series XP Valve Spring Set is designed to handle the stresses of championship-level racing, providing a significant upgrade over stock components.
