This overdrive package adds up to a much improved driving experience. The engine is less stressed on the highway, which means you’re less stressed, and the ride is quieter with lower engine speed and less fuel consumption. A higher numerical first gear makes it easier to pull away from a stop in everyday driving, and it quickens launch times in all types of racing.
