P2uned Billet B58 Water Neck
P2uned Billet B58 Water Neck Save yourself the headache that can occur if your charge pipe coupler fails. This billet water neck replaces the plastic unit right below the charge pipe. If the charge pipe ever blows off, the plastic water neck underneath is sure to crack. This billet replacement is an exact copy of the plastic OEM unit. Have peace of mind knowing you'll never be stuck with a broken water neck.
