Description

Designed specifically for Honda and Acura K-series VTEC engines, the Skunk2 Racing Alpha Valve Spring Set (Part Number 311-05-1380) offers exceptional valvetrain stability and performance at high engine speeds. Manufactured exclusively from super-clean chrome-silicone wire milled in Japan, these springs are engineered for durability and precision. Each set includes 16 springs, featuring a seat pressure of 62 lbs at 1.975 inches and an open pressure of 220 lbs at 1.100 inches, ensuring optimal valve control during aggressive driving or racing conditions.
