BLOX Racing 103mm Billet Throttle Body - Chevrolet LS3 - Black Anodized

BLOX Racing is known for making well-built performance engine components. This 103mm billet throttle body is a prime example, designed specifically for Chevrolet LS3 engines. It's a direct replacement for your stock throttle body, but with a larger bore that can help improve airflow into your engine, especially when paired with other performance modifications. The larger opening allows more air to enter the intake manifold, which can lead to better throttle response and potentially more power.

This throttle body is machined from a solid block of aluminum for strength and durability, then finished with a black anodizing process. This not only looks sharp under the hood but also helps protect the aluminum from corrosion. The 103mm bore is a popular size for LS3 builds looking to maximize airflow without going excessively large. It's designed to fit right into the factory intake manifold location, simplifying the installation process. While it's a direct fit for the LS3, it's important to note that this part is not CARB approved and cannot be shipped to California.

When installing a larger throttle body like this, it's often a good idea to ensure your engine's computer (ECU) is tuned to take full advantage of the increased airflow. This helps optimize fuel delivery and ignition timing for the new setup. This throttle body is a solid option for anyone building a performance LS3 engine and looking to improve its breathing capabilities.
