Collection: Air Intake Systems

We often tell people replacing your intake is the first modification you should do to your car. Often the factory airbox is restricting, especially on older vehicles. Replacing your intake system with an aftermarket unit will increase engine noise, performance, and improve the driving experience. At throtl, we have the top Air Intake Systems from the top manufacturers, including K&N, AEM, Injen, and many more.
