A larger throttle body is key to producing additional power throughout the power band on modified engines with increased airflow demands. The new Grams Performance and Design MKIV throttle body features a large 70mm bore, which results in significant horsepower gains throughout the power band on heavily modified, naturally aspirated applications and even more on forced induction ones.
