About Air Filters
If you're looking for an upgrade from your stock air filter, consider a performance air filter from NAPA Auto Parts for your Scion xB. A performance air filter will provide your engine with plenty of clean air, resulting in increased horsepower and torque, as well as improved fuel economy. Plus, it'll help extend the lifetime of your engine by blocking dust and other particles from entering. So if you want to get the most out of your vehicle, a performance air filter is a great place to start.
