FAST Big Mouth Throttle Bodies

Maximum Air Flow for Increased Performance

FAST's Big Mouth Throttle Bodies increase airflow through a series of innovative design changes and an enlarged throttle opening. These throttle bodies offer larger throttle blade thickness to eliminate deflection commonly found with other throttle bodies, especially those in boosted applications. A smoother operating offset blade pivot improves throttle response, and a beefed-up linkage and dual throttle spring mechanism will ensure total throttle control. Constructed using high-quality billet aluminum, FAST Big Mouth Throttle Body will deliver bolt-on horsepower with a durable, robust design.
