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.

The method of claim 16 wherein: the first portion has an associated first mating surface; the second portion has an associated second mating surface; and an alignment feature is integrally formed with the first or second portion and aligns and maintains a gapped relationship between the first and second mating surfaces. 18. The method of claim 17, wherein the mating surfaces of the first and second portions are generally nonplanar. 19. The method of claim 17, wherein the mating surfaces of the first and second portion comprise at least one tongue and groove relationship. 20. The method of claim 17, wherein the alignment feature includes a projecting portion of the first mating surface or second mating surface. 21. The method of claim 17, wherein the alignment feature includes a recessed portion of the first mating surface or second mating surface. 22. The method of claim 17, further comprising a mechanical attachment for joining the first and second portions. 23. The method of claim 17, wherein said joint is substantially free of mechanical fasteners. 24. The intake manifold assembly of claim 17, wherein the alignment feature is configured of a recessed portion having a width or diameter that is smaller than the dimension of an opposing angled projection thereby preventing completed nestling of the first and second mating surface such that the gapped relationship is formed. 25. The method of claim 17, wherein the alignment feature is configured of a pair of opposing angled projections extending from the second component thereby preventing the complete nestling of the first and second mating surfaces such that the gapped relationship is formed. 26. The method of claim 17, wherein the alignment feature is configured of a projection extending from the second component and located between runners of an intake manifold assembly such that complete nestling of the first and second mating surfaces are prevented such that the gapped relationship is formed. 27.
