These necks feature port provisions for two 1/4 inch NPT intake manifold bypass fittings, one 1/2 inch NPT water temperature gauge fitting, and the ability to mount the main body positioning the outlet to the left side or right side. CNC machined from 6061 billet aluminum for the cost of other similar cast aluminum kits. Available in four outlet hose sizes, 1.250 inch O.D., 1.500 inch O.D., -12 AN male, and -16 AN male, and four finishes, polished, clear anodized, black anodized, red anodized.
