Patent ID: 8631574

Claim:
A method for forming intake manifolds for internal combustion engines and for fastening such manifolds to the engines, comprising: molding a plurality of identical intake manifolds, each one of the intake manifolds being molded with at least one hollow spigot extending outwardly from an outer surface of each one of the manifolds, each one of the spigots being molded with a break-off cap region at the distal end to seal the distal end of the hollow spigot; permanently breaking away the break-off cap region at a selected one or ones of the spigots while leaving the cap on unselected one or ones of the spigots; fastening each one of the intake manifolds to a corresponding one of a plurality of internal combustion engines; and for each one of the fastened intake manifolds, attaching a hose or hoses to the distal end or ends of the selected one or ones of the plurality of spigots.
