Dinan's High Flow Throttle Bodies improve intake airflow for additional horsepower and torque gains. The internal diameter of the stock throttle body is bored 9% larger increasing the airflow area. The resulting increase in airflow provides more horsepower and torque throughout the RPM range with noticeably quicker throttle response.


  • More Power: + 6 HP @ 6500 RPM, + 5 LB-FT @ 6500 RPM (coupled w/ engine software)
  • Improved throttle response
  • Bored 3mm larger for a 9% increase in air flow area
