This drive system is paired with the finest throttle body technology in the industry.  This all new technology features a proprietary cap and motor. The complete drive-by-wire unit features CNC-machined, 6061 aluminum construction, an 80mm inlet and a 72mm outlet. Each system features proprietary internals that allow for increased airflow without sacrificing the smooth throttle characteristics Honda & Acura owners expect. The key is a larger throttle body producing additional power throughout the powerband on modified engines demanding increased airflow. Grams Performance's drive-by-wire systems for K-series engines feature a large bore, resulting in significant horsepower gains on naturally aspirated and forced induction applications.
