Audi S3 1.8T 20V 1999-2003 TURBOSMART Uprated Dump Valve BOV

The Audi S3 1.8T 20V 1999-2003 TURBOSMART Uprated Dump Valve BOV is a top-tier performance enhancement for your vehicle, designed specifically for Audi S3 1.8T models. This high-quality dump valve, manufactured by Turbosmart, features a dual outlet design that optimizes engine performance and sound quality. With its unique dual port configuration, this BOV offers a seamless transition between quiet driving and powerful exhaust note, ensuring a balanced driving experience.

Key Features and Specifications

This Turbosmart BOV is equipped with a dual port design that vents both to the atmosphere and back into the air intake. This sequential timing allows for a quieter operation during normal driving while still providing all the benefits of a vent-to-atmosphere BOV under race conditions. The dual outlet-type BOV is easily convertible to a full atmospheric or full bypass unit, giving you the flexibility to tailor the exhaust note to your driving style. The included port blanking plug simplifies the conversion process. For twin-turbo applications, such as the Audi S4 2.7L (B5) 97-01, this BOV requires two valves for optimal performance.

Supplied and Fitment Information

The Turbosmart Uprated Dump Valve BOV comes with a port blanking plug and a pink spring rated from -24 to -14 InHg, ensuring a secure installation. This product is specifically designed to fit the Audi S3 1.8T 20V models from 1999 to 2003, enhancing the overall performance and aesthetics of your vehicle. With this dump valve, you can expect improved engine responsiveness, reduced turbo lag, and a sportier exhaust note. Upgrade your Audi S3 today with this top-quality Turbosmart BOV and experience the difference in performance and sound quality.
