Skunk2 Ultra Dual Valve Spring & Spring Base Kit - Honda L15B7 / L15CA 1.5L Turbo

Skunk2's Ultra kit adds dual valve springs and spring bases to Honda's L15B7 and L15CA 1.5L turbo engines, allowing more camshaft lift than the OEM springs permit and supporting high-lift performance cams. The springs are wound from high-tensile chrome-silicone wire, shot-peened and heat-treated for consistent long-term valve control.
