About this part

Product Details

If you're looking to get more air into your GM Gen III or Gen IV engine, especially if you've already upgraded your intake manifold, this FAST 102mm Big Mouth Throttle Body is a solid choice. It's designed to work with FAST LSXR, LSXRT, and LSXHR intake manifolds, or any other manifold that can accept a 102mm or larger inlet. The goal here is simple: more airflow means more power, and this throttle body opens things up considerably, with an opening nearly 40% larger than stock.

Beyond just the size, FAST put some thought into how this throttle body operates. They increased the throttle blade thickness to prevent deflection, which is especially important if you're running forced induction. You'll also notice a smoother operating offset blade pivot that helps improve throttle response. Plus, the linkage and dual spring mechanism are beefed up to ensure you have solid control over the throttle, even with the increased airflow.

This version comes in a clean anodized black finish and does not include the Throttle Position Sensor (TPS) or Idle Air Control (IAC) valve, so you'll need to reuse your existing ones or source them separately. Keep in mind this part is not CARB approved and cannot be shipped to California.
