If the original air filter housing is anything like what i have on the gtv, it just has an open hole in to the wing and thus makes the filter housing useless when used wth a cone filter as you no longer have a pull of air.

If the cylindrical filter housing is ported to the front of the car this then creates air flow straight at the filter and this makes this worth keeping. However, its best to port cooler air other than allowing your car to suck in warm air from around the engine bay, i was told that this can increase fuel consumption due to somthing about air being more dense when warm. google it.
