Racing Auto Parts
One of the most popular uses for aftermarket auto parts is in the motor sport industry.
This is due partially because many types of aftermarket high performance parts are illegal for use on public roads, but mostly because the addition of aftermarket parts can greatly improve the performance of a vehicle.
In fact, aftermarket parts are so common in racing that races that comprise only of vehicles that have no aftermarket racing parts is its own sub genre of racing, known as stock car racing.
Performance Parts for Street Use
The other use of aftermarket auto parts is the use of street legal aftermarket racing auto parts. These parts are split up into performance auto parts and replacement auto parts.
These performance auto parts are known as aftermarket parts and are made to increase some aspect of your vehicles performance while keeping it street legal.
However, vehicles built for racing may still use parts that are street legal and many completely street legal cars are used for racing.
One of the most common street legal performance aftermarket auto parts is the turbocharger. The turbocharger is a device that uses the exhaust gases to power a compressor which compresses air and sends it to the engine.
This allows more air to enter the engine per piston stroke, which gives the engine more power. Another popular aftermarket auto part is the addition of a high performance muffler.
Stock mufflers slightly slow down exhaust gases exiting the engine. This produces unwanted back pressure going into the engine. This can lower the power of your engine and thus your cars performance in general.
High performance mufflers reduce this unwanted back pressure while still muffling the engine noise to a level that is acceptable for use on public roadways.
The replacement auto parts are non-OEM parts made to replace existing parts if they begin to malfunction or are broken completely. Examples of such include if your headlights go out or if your power window begins to malfunction.
The reason for buying the non-OEM aftermarket replacement auto parts are usually simply because they are cheaper.
This has caused a good amount of controversy because insurance companies have a history of buying the cheapest replacements they can find, and thus usually buy ineffective parts.Printed From http://www.articlesbase.com/cars-articles/uses-and-types-of-aftermarket-auto-parts-5387958.html
