Moroso billet aluminum filler necks allow you to install a variety of bolt-on style filler necks or block-off plates, offering cooling system flexibility for both race and street applications. The base locates the filler neck at the highest point, to bleed off air on cars with low-mount radiators. They include a machined port for installing a water temperature sending unit, and two ports to plumb return lines on popular aftermarket heads. And, to give you versatile mounting options--these filler necks can be flipped 180 degrees for either a left or right water hose outlet location.
