FAST Racing Big Mouth Throttle Bodies

Product images may differ from actual product appearance.

When it comes to improving performance, increased airflow is a key ingredient. The Big Mouth Throttle Body increases airflow through a series of innovative design changes and slightly enlarged throttle opening. Significant testing and engineering was conducted to optimize cross-sectional flow and eliminate airflow turbulence, especially at part-throttle operation.

The throttle blade's increased thickness eliminates deflection, especially in boosted applications. To improve throttle response, the blade pivot is offset, while the beefed up linkage and dual throttle spring mechanism ensure total throttle control.
