    You may sometimes see airboxes described as "still air boxes" and AFAIK one of the original design objectives was to provide a relatively still (as opposed to turbulent) pool of air for the induction process. Airboxes (at least, some airboxes) then developed the additional benefit of ram air whereby the air pressure inside the box became higher than ambient pressure - passive turbocharging.

    My experience is less in cars than in motorbikes where very significant increases in power come from a well designed airbox with properly placed and shaped intakes. Name:  Airbox 3.jpg

    On the contrary, I've seen quite a few bikes where owners have removed the airbox in favour of pod filters and the results have been tragic - almost invariably a loss of peak power, very poor throttle response and inconsistent fuelling.

    The engine bay of a motorbike is a rather different place to that of a car, particularly as car engine bays are increasingly shrouded so I could accept that the whole engine bay is becoming in effect a giant still air box and maybe even a giant ram air box.

    But I would be fairly cautious about removing what the manufacturers have put so much technology into building.

    Regards
    Bryan

    If you move your air intake duct to a high pressure area of the vehicle (the apex of the bumper or base of the windshield are typical ones), you could achieve this, but the effect on performance would be very small, like a fraction of a psi which might gain you 1 hp and you already have to be doing 40+ mph to get that extra power.

    Julian Edgar of http://www.autospeed.com/ has done a fair amount of testing on different vehicles. He has some great write ups on his website. Here are some good ones:

    Thanks for finding that CheezyWedges. I'll add it to the parts index.

    Does it fit exactly, or is this filter one that is 'close enough' and fits?

    According to K&N's compatability list, Mitsubishi used this filter on the old Mirage, Lancer, and Lancer EVO even (as well as a couple others)...

    http://www.knfilters.com/search/appl...x?prod=33-2105

    Also, these are the Mitsubishi part numbers it replaces:

    Mitsubishi 1500A023
    Mitsubishi MR552951

    So, I'm pretty confident it is the filter we want.
