Dinan’s High Flow Throttle Body improves intake air flow for additional horsepower and torque gains.
The internal diameter of the stock throttle body is bored larger for a 9% increase in air flow area. The resulting increase in air flow provides more horsepower and torque throughout the rpm range with noticeably quicker throttle response.
*Dyno results for the combination of Stage 3 Performance Engine Software, High Flow Cold Air Intake, Free Flow Exhaust and Throttle Body.
