Z3 Turbo Kit Sonic-Cruze Cross-Drilled Designs - ChamferedThis kit has been engineered as the most complete, best warranted, highest supported turbo kit in our market (Impala, Monte Carlo, Grand Prix, Regal, & Bonneville). When compared to the positive displacement supercharger that is factory installed on these vehicles, turbos are far more efficient with less parasitic loss and less heat in the discharged air. This results in better drivability at high horsepower levels and, overall, better performance.
