Feed Your LS Engine More Power-Building Airflow a FAST Big Mouth 102mm Cable-Drive Throttle Body

Designed for GM LS Gen III and Gen IV engines with cable-driven throttle bodies, The FAST Big Mouth 102mm Throttle Body features a 40% larger air inlet than stock. That allows it to deliver a massive increase in airflow while maintaining stock idle characteristics. Other features include:

• Thicker throttle blade to eliminate deflection in boosted applications
• Offset blade pivot improves throttle response
• Stronger throttle linkage with dual throttle spring mechanism
• Available with or without a TPS sensor and Idle Air Control motor
• Black anodized finish

The FAST 102mm Big Mouth Throttle Body is ideal for use with FAST LSXR, LSXRT, or LSXHR intake manifold, as well as other manifolds with a 102mm or larger inlet.
