What is the main benefit of an aluminum filler neck over a stock plastic one?

Aluminum filler necks are generally more durable than plastic ones, offering better resistance to heat and potential cracking over time. This can lead to a more reliable seal for your cooling system.

Does this filler neck come with any hardware or seals?

This part is the aluminum filler neck itself. It is designed to use your vehicle's existing mounting hardware and seals. Refer to the manufacturer's installation instructions for details.

What is the purpose of the filler neck in a cooling system?

The filler neck is the point where you add coolant to your radiator or expansion tank. It also provides a seal for the system, helping it maintain the correct pressure for efficient cooling.
