Polyamide air intake manifold saves costs, adds performance

Fig 1 The glass fibre reinforced polyamide manifold can withstand dynamic burst pressures of up to 10 bars, meaning it is unaffected if an engine should backfire. A new design of injection moulded air intake manifold, developed in France by Rhodia Engineering Plastics and Mark IV Automotive, is being used on two Sports Utility Vehicles (SUV) being produced by Ford in the US. The component is significantly cheaper than similar plastic manifolds and provides improved engine performances.
