If your vehicle is running a little rough and losing power on the hills, your Saab air filter is a good place to begin in the search for the source of its bad behavior. A clogged Saab air filter can cause all sorts of performance issues in your vehicle. The engine needs a mixture of air and fuel to produce the combustion that makes it run. More to the point, it needs a precise level of each one to perform at its most efficient. The purpose of the Saab air filter is to clean the air that enters the engine, removing any particles of dust, dirt or debris that it may be carrying before it enters the engine, where the abrasive particles could cause expensive damage. As it does its duty, the Saab air filter collects this debris on its surface, and will gradually become covered with the dirt it intercepts. As this happens, the airflow that passes through the Saab air filter will decrease slowly. If left unchanged for a long enough period, the Saab air filter will become clogged and choke off the air that your engine needs to run at its best. This lack of air can cause rough running and idling, a loss of engine power, and poor fuel efficiency among other symptoms. There is no reason to tolerate such bad behavior from your vehicle, since you can help to shape it up quickly and easily with just a few minutes of your time and a new Saab air filter.
