FX1 Intake Systems are specifically engineered to deliver peak horsepower and torque. This is made possible by drawing air from an isolated area away from the heated engine compartment. So with the induction of cool air, the engine responds more efficiently, the power band is raised, and peak horsepower and torque are raised. Each kit comes with all necessary hardware, including CNC machined brackets that are tig welded to the intake. FX1 Cold Air intake are made from 6061 high quality aluimum to reduce heat and weight to the xB. Why pay more for same performance on the cold air intake system. This system will also fit all Scion xA model. Cold Air can be converted to short ram only.
