How to Buy an Air Filter for a Saab 9-3

An automobile is one of the large investments a person can make, so it only makes sense that taking care of that investment is a priority. Properly maintaining a vehicle can dramatically increase its lifespan and reduce repair costs over the long term. Something as simple as regularly changing engine oil can prevent engine failure and very expensive repair later on. One of the more often overlooked items that should be replaced regularly is the air filter.

 Ironically, the air filter is an easy item in the engine compartment to replace, yet it is frequently overlooked. It is the main component that stands between the internal workings of an engine and the air that is sucked in to help it breathe. Without a properly-functioning air filter, the engine works harder than it should, causing problems eventually. Having a spare air filter on hand should always be a priority for a vehicle owner. Although air filters are easily available through auto parts stores, one can also utilise the advanced shopping tools available on eBay to find the right air filter for a vehicle at a reasonable price.

About the Saab 9-3

The Saab 9-3 was produced from 1998 until 2012, making it one of the more popular platforms that Saab has produced. The 9-3 is considered a compact executive car; it was available in a two-door convertible, a three-door coupe, a five-door hatchback, a four-door saloon, and a four-door station wagon. The Saab 9-3 was available in a five-speed manual transmission, a five-speed automatic, a four-speed automatic, a six-speed manual, and a six-speed automatic as well as three different engine sizes.

The car was designed from the beginning to be a replacement for the ubiquitous Saab 900, which had been produced for the previous 20 years. Saab made substantial changes to the 9-3 in the areas of handling and safety, making it a worthy successor to the 900. There are many Saab 9-3 vehicles still on the road today, and owners can take advantage of the tools available online to find the maintenance items they need to keep the cars going strong.

Importance of the Air Filter

Air filters serve different purposes in the operation of a vehicle and maintaining the comfort of occupants. A car engine is basically a large air pump that takes in air and mixes it with fuel to create combustion.. This action drives the pistons and turns the crankshaft. The air-to-fuel mixing ratio is a vital part of a properly running engine. An old and dirty air filter can prevent fresh clean air from entering the combustion chamber and can even allow dirt to be inducted into the chambers and contaminate the air-to-fuel mixture. When the air-to-fuel ratio is disrupted, the result is poor operation of the engine that leads to reduced performance, lower fuel economy, and eventual harm to the engine. The more frequently the engine air filter is replaced, the better the engine runs and fewer problems result.

Types of Air Filters

More than one type of air filter is located in most modern vehicles. The engine air filter is located in the engine compartment, but the cabin air filter is located inside the cockpit of the vehicle, helping filter air to the interior of the car.

Engine Air Filter

Engine air filters are constructed from various materials that serve the purpose of filtering the external air coming into the Saab 9-3 engine. The filter traps particles or dust, preventing them from entering the combustion chambers of the engine. When particles get into an engine's cylinders, it contaminates the oil and causes premature wear, which results in damage and eventual failure of the engine. Air filters allow clean air to pass into the chambers and mix with fuel to create a proper chemical combustion. When this occurs, the engine works at peak efficiency. When dirt contaminates the process, fuel economy suffers, and power loss becomes apparent. Simply replacing the engine air filter at regular intervals can keep an engine running at its best.

Cabin Air Filter

The cabin air filter on the Saab 9-3 is similar to an engine air filter in that it is constructed to prevent particles from passing from the exterior of the vehicle into the interior through vents. The filter also scrubs the air inside of the vehicle when the air conditioning is active and the air recirculation setting is on. Cabin air filters specialise in trapping dust and pollen that frequently float in the air around roadways. The cabin filter also traps larger debris such as hair and any other small particle that tries to enter through the vent or is recirculated in the air conditioning system. Frequently changing the cabin air filter keeps the air inside of the vehicle much cleaner for the occupants.

Materials Used to Make Air Filters

Different types of materials are used to construct air filters. Cabin filters are usually constructed out of paper, much like other air filters, but cabin filters feature more intricate layering since they must filter out microparticles such as pollens and spores and prevent them from entering the cab. Paper is a common choice for air filters because it is effective, inexpensive, and very efficient at cleaning the air prior to induction. Another material used for engine air filters is oil-wetted foam, which is frequently used in areas of heavy dust. The oil base in the foam serves to trap and contain larger amounts of dust, and this is frequently used for off-road applications or in construction vehicles. A new type of air filter is based on cotton gauze that is oiled, and it works in a similar fashion as the foam filter. This type of filter is considered acceptable in high-performance applications.

Considerations When Buying an Air Filter for a Saab 9-3

An owner of a Saab 9-3 should inspect the car's air filters on a regular basis. This includes the engine air filter as well as the cabin air filter. These should be replaced as soon as any sign of dirt build-up is noticed. The engine air filter on the Saab 9-3 is located in a large black box on the passenger side of the vehicle and can easily be replaced. The cabin air filter is located on the same side, just behind the top of the strut towards the rear of the engine compartment. Both black box containers can be easily opened so the filters can be inspected and replaced when necessary. By buying these filters and replacing them at home, owners can save a lot of money every year in maintenance costs by not taking the vehicle into a shop to have it done. Making sure that the right filters are purchased is the most important step, but the tools available in the marketplace make this process simple.

How to Buy an Air Filter for the Saab 9-3 on eBay

If you have decided to buy an engine air filter and cabin air filter for your Saab 9-3, you can find the right filters and purchase them using the powerful search tools available on eBay.
