Performance Parts
The term Performance Parts generally refer to any component that replaces an original equipment manufacturer (OEM) part with one that has superior features. The part may be more durable, more attractive, or may increase the performance of your vehicle in some way. The manufacturers of performance parts will usually make some claim as to what improvements their parts will make, and they may have test data to substantiate their claim.
While many reputable companies sell performance parts, it's important to do your own research to see if others have had success with the same components. The availability of performance parts depends on the make and model of the vehicle. Cars that are generally considered sports cars usually have a broader selection of parts available than four-door family sedans. If you own a car that is popular among high performance enthusiasts, you can be sure there is a long list of available performance parts. Even common economy cars will have something available that is considered a performance part. Aftermarket performance parts fall into just about every category you can imagine, from paint to pistons.
Engine performance parts usually claim to improve power output. High compression pistons, lightweight connecting rods, high lift camshafts, and oversized valves are some examples of mechanical components that can improve performance. While a forged crankshaft may not improve engine power compared to a cast crankshaft, the improved strength and durability justify the performance designation. Enthusiasts looking for big power gains may even consider things like superchargers or turbochargers.
Exhaust headers, high flow mufflers and catalytic converters, cat-back exhaust systems, and ceramic exhaust coatings are examples of performance exhaust parts that can improve your car's acceleration and top speed, along with giving you a sportier sounding exhaust note.
When it comes to electrical and electronic parts, spark plugs, ignition coils, distributor caps, and user programmable engine management computers are just a few of the components that can make your car faster. Other electrical parts that are available and considered performance parts include headlamp bulbs, tachometers, and gauges. While these latter components may not improve your car's speed or acceleration, they may offer improvements in visibility or response when compared to the stock components, hence the performance designation.
When it comes to your car's chassis, the list of available performance parts is also long. Shock absorbers, springs, anti-sway bars, and suspension bushings are just a few of the things that might improve traction, allowing your car to accelerate or turn better. Add to this the list of lightweight wheels and wider or stickier tires that are available for just about any car, and you'll see that just about everyone can find something for their vehicle that can be considered a performance part.
The term performance part, in fact, can be applied to just about anything you might consider changing on your car. There are even high performance car waxes and paints that claim to be more durable or fade resistant. Car stereos and floor mats can also be included. The list is limited only by your imagination.
