Let's identify and discuss briefly the use of some of these new auto parts and the importance of these products to your vehicle's ultimate driving performance.

AC Compressor. This is a part of the AC system. It performs a vital task of moving the liquid around the pipe. It pumps and forces the liquid or the refrigerant gas out from the evaporator where it absorbed the heat coming from the car's cabin. In the compressor, the gas is compressed before it is transferred to the condenser where actual heat dissipation occurs.

Oxygen Sensor. This particular auto part is an essential part of the exhaust system. It is a hollow tube that is inserted into the exhaust manifold to measure how much oxygen is present in the exhaust so that the computer can either add or subtract certain amount of fuel to obtain an adequate mixture of air and fuel. A high quality oxygen sensor can help you achieve maximum fuel economy and efficiency.

Projector Headlight. These are special types of headlights that produce stronger beam and a more focused illumination; thus these headlights have less "scatter loss." It is named as such because it was designed like a slide projector.

Headlights and other auto lights are very important to one's safety; thus, they are essential in every vehicle. Aside from keeping the car visible as it moves down the road, lights provide illumination for you to drive by, signal other drivers that you are going to stop, turn or move to another lane.

Mud Guard. Among the many useful accessories in a car, truck, SUV or van are the mud guards. Although these auto parts or accessories may not totally or significantly affect the performance of your vehicle, these are essential in keeping your vehicle clean and away from impurities such as mud, slush and stones that could speed up deterioration or corrosion of other parts in your vehicle.

Towing Mirror. These are special types of mirrors that are used to aid in towing. They may be used to replace or they may be attached to the outside mirrors to provide additional visibility and safety.
