Description
Requires modified throttle body hose.
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 MK4 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.
Not for sale or use in the state of California on any pollution-controlled vehicle as per the California Air Resources Board.
