A large variety of intake manifolds were installed on Gen III/IV engines. Cross-compatibility issues arise in cable- versus electronic-throttle provisions, not to mention exterior manifold dimensions possibly interfering with installation into a given vehicle. Here we see, from left to right, an LS2 car intake (electronic), LQ9 truck intake (cable), and L76 truck intake (electronic). Some engines had a different style intake depending on the vehicle they were installed in. For example, LS2s installed in trucks had taller truck-style intakes. (Note that an LS9 or LSA has a supercharger in place of the intake manifold.)
