  • a problem with such known air cleaners and intake manifolds is that such components are separate and distinct. Such separateness and distinctness can result in mechanical incompatibility between such components, the need for additional hoses and tubes to connect such components, decreased accessibility to such components for servicing and a reduction in the physical underhood space available for accessory components.
