Audi S6 / RS6 4.0 TFSI Upgrade Throttle Body

Audi S / RS 4.0 TFSI Upgrade Throttle Body

The ultimate upgrade for your Audi 4.0 TFSI engine. This upgraded throttle body is designed to significantly improve airflow and unlock extra power in tuned vehicles. Thanks to its enlarged intake ports, this throttle body delivers a noticeable improvement in throttle response, turbo pressure, and overall engine performance — ideal for those who want to take their Audi RS6, RS7, S6, S7, or S8 to the next level.

The throttle body features enlarged air intake bores from 39.8 mm to 48.6 mm, resulting in increased airflow and a power gain of approximately 20 to 30 hp when used in conjunction with a custom turbo or ECU setup. The more efficient flow allows the engine to breathe better, leading to faster acceleration and smoother power delivery.

This performance throttle body is built using original OEM parts and is fully compatible with Audi's original silicone hoses. Installation is plug-and-play, with no modifications required. Because original throttle bodies are used, minor signs of use may be present — this does not affect functionality or quality.

If you choose the exchange option, you must first send your original throttle body to the manufacturer. Once received, the upgraded version will be shipped.
