to answer your question...the pre heat hose is useless unless in cold temps. It allows the engine to heat up faster in cold temps. I beleive the thermostat in the air filter box begins to allow heated air in...at around 40 degrees F or lower. It sometimes jams opens(the thermostat in the box) and allows heated air to continiously flow insde....damaging the air mass meter (expensive part) as well as causing other perfomance problems. I woudnt' worry about the hose unless you are in a state that requries it for emissions testing. I woudl check the thermostat to see if it's stuck open as well(only if the temp is above 40 or 50 shoudl it be fully closed).


About the other hose. Connected to the air filter box there are two hoses. One extends towards the front (outside) of the car towards the grill. this is the hose that sucks in air. This hose is not connected to anything...it's simply to draw in air. Then there is another hose that goes from the part of the air filter box all the way to the intake manifold(this is the hose that is towards the inside of the car rather than pointed towardst he outside. All parts of this hose going towards the intake manifold need to be on snugly. If its not connected its allowing unfiltered air in which will lead to somewhat more engine abrasion and wear.


Anyways...good luck
