  • Engine intake manifold assembly
    Patent number: 7360519
    Abstract: An engine intake manifold assembly including a first portion configured with a first material and a second portion configured with a second material, wherein the first and second portions are adhesively bonded together. Preferably, the intake manifold assembly is additionally configured with a cylinder head flange, for mounting the same to an automotive engine component, and a throttle body attachment for attachment of a throttle body component. The cylinder head flange and throttle body attachment may be an integral component of the first or second portions or attached to the same during or after assembly of the first and second portions. Optionally, an insert is located between the assembled first and second portion to create one or more plenums thereby creating one or more air flow paths through the intake manifold assembly.
