The air filter on my car is held between two pieces of plastic (one goes to the engine, the other goes out to the front of the car). I removed the side that goes to the front of my car, and attached the air filter so that it is completely open (but filtered). I feel like doing this has given me better gas mileage. The car is louder, but I am wondering if the change I made could harm my car.
