Supertech beehive valve spring engineered for the Toyota G16E-GTS 1.6L turbo triple. The tapered beehive profile trims reciprocating mass and resists valve float at high rpm, letting the engine rev cleanly with upgraded cams or raised boost. It is a durable replacement for the fatigue-prone factory springs on built and tuned motors.
