Hypertech?s Interceptor is a smart technology design that works with today?s generation of complex engine computers. The Interceptor easily mounts under the hood of a vehicle and plugs into the factory harness to constantly monitor the vehicle?s functions. The Interceptor then automatically recalculates the factory?s computer performance calibrations with legendary Hypertech Power Tuning. This means more horsepower and torque, quicker acceleration, better driveability, and improved MPG.
