    IIRC the pipes help to reduce the noise of the engine. im not sure but they may also help to reduce emissions

    Well, I'll try !! :P


    The pipes and the long route that air actually takes to get into the engine is done for a number of reasons by vauxhall ( and most other manufacturers).

    In the airbox, the pipes restrict the actual volume of air getting in, and by design they possibly shape the route that the air flows inside the box to a point. We derestrict simply to get a larger volume of air in, and we're less bothered about the route the ar takes.....although I suppose it could be important to get an even swirl flow that flows across the whole of the panel filter rathe rthan intensifying in one area.

    One of the main reasons is to reduce power.
    i.e. the 1.6 16v engine could have had more power than a 1.8, so the inlet manifold was made more complex to restruct the power for the eninge, making it fit in with the target for the 1.6.
