* Cylinder heads. The cylinder heads, which cover the top of the engine block and contain the valves, are also often made of aluminum for the same reasons.
* Intake manifold. The intake manifold, which delivers air and fuel to the engine, is often made of aluminum because it needs to be lightweight and able to withstand high temperatures.
* Exhaust manifold. The exhaust manifold, which carries exhaust gases away from the engine, is often made of aluminum because it needs to be lightweight and able to withstand high temperatures.
* Transmission housing. The transmission housing, which contains the gears that transfer power from the engine to the wheels, is often made of aluminum because it is lightweight and strong.
* Suspension components. Some suspension components, such as control arms and wishbones, are often made of aluminum because they need to be lightweight and strong.
* Wheels. Some wheels are made of aluminum because they are lightweight and strong.
* Body panels. Some body panels, such as hoods, fenders, and doors, are often made of aluminum because they are lightweight and strong.
