I live in Mn and it is 4 below without the windchill. I couldn’t get my lighter to lite so i but it in between the vents. It fell through. Tried to get with tweezer but couldnt get it and fell somewhere. Should I be worried? Pontiac sunfire 2003. Thanks Dan

Does The Air From The Vents Pass Through The Filter?

Under the hood, there is a filter, called an “air cleaner element”, to keep dirt, sand, etc., from entering the engine. Does the air that comes out of the vents (heating / air conditioning) into the passenger compartment (a) come from this intake and pass through the same filter, (b) come from another intake and pass through a different filter, or (c) come from a different intake and not get filtered?
There are tiny specs of something in the air coming from the vent. Does this mean that I need to replace the filter on the air going to the engine?
