Hi THey claim that a K&N filter would improve fuel economy. What I would like to ask the community is if K&N increases air flow, shouldn't the computer adjust to put more fuel to make the mixture right?. So maybe you get more power but how can it get better fuel economy. Anybody with experince in the matter ? Thanks in advance

False.
Which it does not, at any airflow level you'll experience in a Grand Caravan 3.3. A K&N will, however, increase the amount of dirt reaching your engine.
