If your vehicle is having performance problems, finding the source of your vehicle's problems is best done by checking the simple things first, such as the Saturn air filter. Often it is the little things, their importance too often underestimated, that cause such nagging problems. If your engine is not running its best, don't assume the worst, check the Saturn air filter before you look for more complicated mechanical failures. You will probably be surprised at the array of problems the neglect of such a small, inexpensive - especially when you shop with us -- thing can cause. A dirty or clogged Saturn air filter can cause your vehicle to run and idle roughly, and even to misfire. Your vehicle could lose power, consume an excessive amount of fuel, and you might notice an excess of exhaust smoke. All these can be symptoms of an imbalance in the air and fuel ratio your engine is receiving. The engine requires a precise level of both fuel and oxygen to produce efficient engine combustion. If it receives less than it needs of either, performance is diminished. Your Saturn air filter cleans the airflow that comes into the engine to provide the oxygen it needs, filtering out particles of dirt and debris that could cause damage to sensitive engine parts. As time passes, the Saturn air filter will gather enough of this matter to restrict the air that passes through it to the engine, causing performance problems if not changed promptly. The Saturn air filter is easily changed, so just a few, regularly applied, minutes of your time can help keep your engine at its best.
