Chase Bays -16AN / -16AN Raised Inline Filler Neck w/Cap
The Chase Bays Raised Inline Filler Neck is engineered to raise the coolant fill point by 3.75 inches (95.25mm) from the center of the lower fitting to the cap seal, addressing common cooling system bleeding issues especially in engine swaps and lowered radiators. It features a total height of 5.25 inches (133.35mm) and installs by welding directly to the upper water neck or using a short hose connection.
Constructed from 6061 billet aluminum, it is bead blasted and anodized semi-gloss black with the Chase Bays logo laser etched on both sides. The filler neck includes a Type A radiator cap, widely used on import vehicles, and has a 4AN ORB threaded overflow port with a 1/4 inch hose barb connection, providing a significant upgrade over typical 1/8 NPT fittings.
