Super Silicone WECS Terminal Boot

By increasing the discharge current at the initial stage, it aims to improve torque at low-to-medium engine speeds while helping to prevent voltage drops in the high-revolution range for smoother power delivery. This upgrade features an earthing system with flash gold plating and utilizes a Super Silicone boot in place of the factory rubber version.
