What is the main benefit of this 102mm throttle body over a stock one?

The primary benefit is a significant increase in airflow. The larger 102mm bore allows your engine to breathe much more freely, especially when paired with performance intake manifolds, which can lead to improved power output.

Does this throttle body come with everything needed for installation?

This throttle body is designed as a direct replacement for the electronic throttle body. While it does not use stock components, it's recommended to consult the manufacturer's installation guide for any specific hardware or sensor requirements not included.

Is this throttle body compatible with older LS engines or cable-actuated systems?

No, this electronic throttle body is specifically designed for GM LS engines that use a drive-by-wire system and stock Gen IV LS ECUs. It is not compatible with older cable-actuated throttle systems.

Product Details

This is the FAST 102mm Electronic Throttle Body, built specifically for GM LS engines with drive-by-wire systems. If you're looking to get more air into your high-performance LS motor, especially when paired with a FAST intake manifold, this throttle body is a solid choice. It's designed to provide a significant increase in airflow over the stock unit, helping your engine breathe easier and make more power, while still maintaining stable idle characteristics.

What sets this throttle body apart is its clean-sheet design by EPG engineers, meaning it doesn't use any components from a stock throttle body. This allows for a full 102mm bore, maximizing airflow with less restriction. It's built with a high-torque motor for quicker response compared to other aftermarket options, and features a dual return spring and a precision non-contact throttle position sensor for improved reliability. The throttle blade is designed to remain steady, which is crucial for boosted applications. Plus, it comes with a stylish satin black anodized finish that looks great under the hood.

This electronic throttle body is designed to be plug-and-play with most stock Gen IV LS ECUs, including popular ones like the L76, L77, L99, LS3, and LS7. It also works well with aftermarket EFI systems designed to control a GM LS-style electronic throttle body, such as the Edelbrock ProFlo4+. Keep in mind that this part is not CARB approved and cannot be shipped to California.
