An electronic method of intelligently absorbing and removing electrical energy to protect your vehicle’s cooling system from the harmful effects of electrolysis. Voltage Sponge is a simple two wire installation that targets the component needing protection, such as attaching to the radiator or heater core without grounding. This continuously works even when the engine is not running and requires no maintenance.
Added benefits include eliminating static shock and static electric energy, which can cause drivability problems.
Voltage Sponge works best with the Rad Cap.
