FAST Big Mouth LT Throttle Bodies

3.78 out of 5 stars 9 Customer Reviews

FAST Big Mouth LT throttle bodies are cost-effective and stylish. If you don't want to go billet or can't afford it, these throttle bodies are the perfect choice for a variety of applications. An enlarged bore allows for increased airflow to support your higher horsepower, a progressive throttle pulley enhances drivability--especially at low throttle--and a double return spring provides a solid feel and increased safety. Here's an excellent alternative with all of the same features as their billet bodies--FAST Big Mouth LT throttle bodies with black wrinkle powdercoating.
