This Moroso filler cap kit comes with an aluminum bung, which is a solid choice for custom cooling setups. The bung is designed to be welded onto your radiator or expansion tank, giving you a secure mounting point for the included filler cap. It's a well-built piece that helps ensure your cooling system stays properly sealed.

The kit includes the aluminum bung and the filler cap itself. You'll need to have this bung welded into place by a professional or someone experienced with welding aluminum. Once installed, it provides a reliable way to maintain the correct pressure in your cooling system, which is crucial for preventing overheating and ensuring your engine runs at its optimal temperature.
