Induction

Refine Results

A vehicle's induction has the job of bringing in clean air to your engine's combustion chamber. This air is then measured and metered to help your vehicle operate efficiently. The induction system is also important in boosting the performance of the engine by working on the gas mileage, increasing power, and reducing emissions. The induction system on your vehicle is composed of the fuel injectors, the intake manifold, the throttle body, intake valves and the air filter assembly. If the throttle body on this system gets dirty it can upset the airflow and lead to decreased fuel economy within your vehicle. You can have your induction cleaned and serviced to prevent problems from occurring. This cleaning process involves cleaning the throttle body, the air intake vales and the fuel injectors. Reviewing your vehicle's manual will give your their recommendation for servicing. Like all parts in your vehicle, there may come a time to replace parts in your induction system. Should you have parts that need to be replaced in your induction system you should purchase only genuine OEM replacement parts. Shop our webstore for these genuine OEM replacment parts for your induction system. You can rest assured that they will be quality parts made for your Mazda vehicle.
