What is the main benefit of a larger throttle body like this one?

A larger throttle body, such as this 103mm unit, allows for a greater volume of air to enter your engine's intake manifold. This can lead to improved throttle response and potentially increase horsepower, especially when combined with other performance modifications.

Is this throttle body a direct bolt-on installation?

Yes, this throttle body is designed as a direct replacement for the factory unit. It utilizes the stock mounting points and electrical connector for your vehicle's drive-by-wire system, simplifying the installation process.

What does 'Not CARB approved' mean for this throttle body?

This means the throttle body does not meet the emissions standards set by the California Air Resources Board (CARB). Consequently, it cannot be legally shipped to or installed on vehicles registered in California.

Product Details

If you're looking to get more air into your 2014-2019 Chevrolet Corvette's LT1, LT4, or LT5 engine, a larger throttle body can make a notable difference. This 103mm unit from Granatelli Motor Sports is a direct replacement for your factory drive-by-wire throttle body, designed to improve airflow and potentially boost performance.

This throttle body features a larger 103mm bore compared to the stock unit, allowing more air to enter the intake manifold. The polished finish not only looks sharp under the hood but also indicates a well-made component. Granatelli has a reputation for producing reliable engine components, and this throttle body is built to handle the demands of performance-oriented GM LT engines. It's a popular choice for those looking to enhance their vehicle's breathing capabilities, especially when paired with other intake or engine modifications.

Installation is designed to be a direct bolt-on process, utilizing the factory mounting points and electrical connector for your drive-by-wire system. While this throttle body is not CARB approved and cannot be shipped to California, it's a solid option for Corvette owners in other states looking for an improved throttle response and increased airflow. Ensure you check manufacturer fitment data to confirm compatibility with your specific vehicle model and year.
