High Flow Throttle Body

High Flow Throttle Body (1997-1998)

Special Note: Stage 3 Engine Software Highly Recommended. Not applicable for 528i (E39) 1999-2000.
Product Description
The internal diameter of the stock throttle body is bored larger for increased 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 Body improves intake air flow for additional horsepower and torque.

*Dyno results for the combination of Stage 3 Performance Engine Software, High Flow Cold Air Intake, Free Flow Exhaust and Throttle Body.
