Discover the BOV Valve Aluminum Dual Port Splitter for VAG 1.8T—the billet aluminum powerhouse designed to manage turbocharged charge air with precision. This 25mm dual port dump valve is engineered to return some of the charge air to the intake to keep the MAF sensor happy, while venting a portion to atmosphere for that characteristic “woosh” that enthusiasts love. Built to improve throttle response and boost stability, it’s a practical upgrade for VAG 1.8T applications and 2.7 Bi-Turbo setups, with a focus on reliability and tunable driveability.

Constructed from high-grade billet aluminum, this BOV is not only capable of handling performance demands but also built to last under daily driving conditions. The top piece is adjustable, letting you dial in preload to harmonize with your engine and driving style. Removable ports give you flexible setup options, including Dual Port (50/50 Atmospheric Recirculation), Full Atmospheric, and Full Recirculation, so you can tailor the valve to your preferences and performance goals. This unit is designed to be a direct replacement for the standard plastic Bosch diverter valve, offering a solid upgrade path without sacrificing reliability.
