Add performance and horsepower by increasing airflow to the motor.

The PERRIN Performance™ boost tube is a direct replacement for the upper boost tube reaching from the throttle body to the cold side of the turbocharger.

The PERRIN Performance™ upper boost tube maintains a constant inside diameter and ultra smooth interior surface. The PERRIN™ boost tube increases the internal diameter of the intake pipe by 15% increasing airflow to the engine. The PERRIN™ upper boost tube will work with all factory replacement blow off valves.

The malleable boost tube can conform to tight places if you are using a larger battery isolator. No need for a battery relocation kit.

Included in the kit are two additional couplers to dress up your front mount intercooler.
