    An intake manifold is an integrated assembly that sits atop the engine, consisting of a series of tubes which distribute fresh outside air to each and every cylinder. On V-shaped engine blocks, an intake manifold typically sits between the two cylinder banks while inline engines may feature a manifold to the side of the cylinder head.

Even if you have a hot rod or custom car, or if your car’s just not listed in a catalog, you can still get a quality system. Everyone, regardless of...
