Billet Water Filler Neck w/1.5 Hose Fitting

The CANTON Billet Water Filler Neck w/1.5 Hose Fitting (MPN 80-005) is a precision-engineered cooling system component designed for builders and enthusiasts who demand both form and function in their engine bay. This billet aluminum filler neck replaces restrictive OEM designs with a purpose-built inlet that accommodates 1.5-inch hose fittings, making it ideal for custom cooling system configurations, engine swaps, and high-performance builds.

Crafted from billet aluminum, this water filler neck delivers superior durability compared to cast alternatives, resisting corrosion and thermal cycling stress that can compromise factory components over time. The precision-machined design ensures a secure seal and leak-free operation, while the compact footprint (9.25 inches in length) makes it adaptable to tight engine compartments without sacrificing functionality.

At just 1.8 pounds, the aluminum construction keeps weight to a minimum, an important consideration for chassis balance in performance vehicles. This billet water filler neck is essential for custom cooling systems, making it a valuable addition for those upgrading their street machines, competition vehicles, or show cars.
