    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.

    Most aftermarket air filters are constructed from multiple layers of cotton gauze, which are sandwiched between wire mesh that is formed into pleats.

No droning sound when cruising along at highways speeds.
