Moroso Weld-On Filler Neck - SAE Type B - Billet Aluminum

Moroso is known for making well-built performance parts, and this weld-on filler neck is no exception. If you're fabricating a custom cooling system or modifying your setup, this part gives you a clean way to add a filler neck. It's designed for SAE Type B applications, meaning it uses a standard neck size that works with many common radiator caps and hoses.

This filler neck is machined from solid billet aluminum, which makes it strong and resistant to corrosion. You'll need to weld this onto your radiator or coolant reservoir, so it's a good choice for custom builds where you need a precise fit and a professional look. The material is durable and will hold up well in the engine bay.
