* Engine type and model: Different V6 engines have different designs and displacement, meaning they'll react differently to modifications.
* Original throttle body: A stock throttle body might already be optimized for the engine. Replacing it with a larger one might not offer any noticeable gains.
* Other modifications: The gains from a larger throttle body are often magnified when combined with other performance upgrades like headers, exhaust, and tuning.
* Installation and tuning: A larger throttle body might need proper tuning to work efficiently. A poorly installed or tuned throttle body can actually decrease performance.
In general, a larger throttle body alone won't significantly increase horsepower on a stock V6 engine. It can be a small part of a larger performance package. If you're considering this modification, it's best to consult with a knowledgeable mechanic or tuner who can evaluate your specific engine and recommend the best course of action.
