Product Description
The internal diameter of the stock  throttle body is bored 9% larger increasing the air flow area. The resulting increase in air flow provides more horsepower and torque throughout the rpm range, with noticeably quicker throttle response.

Dinan's High Flow Throttle Bodies improve intake air flow for additional horsepower and torque gains.
