What is the main benefit of a 103mm throttle body?

A larger 103mm throttle body allows for a greater volume of air to enter the engine's intake manifold. This improved airflow can lead to better throttle response and potentially increase horsepower, especially on modified engines.

Does this throttle body come with everything needed for installation?

This listing is for the throttle body unit itself. While it's designed as a direct bolt-on, it's recommended to refer to the manufacturer's installation instructions for any specific hardware or sensor requirements not included.

Is this throttle body compatible with California emissions standards?

No, this Granatelli throttle body is not CARB approved and cannot be shipped to California due to emissions regulations. It is intended for use in areas where such emissions standards do not apply.

About this part

Product Details

This 103mm throttle body from Granatelli Motor Sports is a direct replacement for your GM LS3, LSA, or LSX engine equipped with a drive-by-wire system. Its larger bore compared to stock allows for significantly more airflow into the intake manifold, which can help your engine breathe easier and potentially make more power, especially when paired with other performance modifications. The polished finish not only looks sharp under the hood but also indicates a well-made component designed for enthusiasts looking to optimize their engine's performance.

Granatelli built this throttle body with a 103mm opening, a notable increase over the factory unit, to support higher horsepower applications. It's designed as a direct bolt-on for compatible GM vehicles, meaning installation should be straightforward without the need for extensive modifications. The drive-by-wire technology ensures seamless integration with your vehicle's existing electronic throttle control system, maintaining smooth operation and responsiveness. This part is a solid choice for anyone rebuilding or upgrading the top end of their LS-based engine and looking for improved throttle response and airflow.

Please note that this throttle body is not CARB approved and cannot be shipped to California. It's important to check your local emissions regulations before purchasing. This component is designed for off-road use or vehicles not subject to emissions testing in states that follow California's standards.
