The induction system takes air in from the outside and provides that air to the engine to mix with fuel to be ignited and power the car. The quality and amount of air put into the engine greatly influences the performance of the car. The induction system uses the computer to calculate the proper amount of air to put into the engine and the air filter ensure that only clean air is used. When the induction system fails, you want to make sure to replace parts as soon as possible. The system is made of many different parts, including the filter, the airflow sensor, and the throttle body. You might have an induction system that has become built up with debris, which can cause problems to different parts. You also might find that your car is starting to take longer than normal to get going. This can be from reduced air flow messing up the combustion process. Another thing that can come from a failing induction system is an increase in rough idles. It's important when making induction replacements that you're choosing parts that will fit your make and model perfectly. Find OEM induction parts here at Honda Acura Parts Direct.
