Product Description

The Turbosmart TS-0204-1303 Bubba Sonic Blow-Off Valve (BOV) is a universal performance turbocharger pressure relief valve engineered for high-flow, high-boost setups. Its oversized 52 mm inlet and outlet provide greater airflow capacity than standard blow-off valves, making it suitable for powerful turbocharged engines and custom builds where pronounced vent-to-atmosphere sound and strong boost management are desired. Precision machining and billet aluminum construction ensure durability while minimizing weight and sealing complexity.

This Bubba Sonic BOV includes an alloy hose adapter/weld flange and V-band clamp for flexible installation options, allowing integration into a range of turbo charge piping. A pre-installed green spring tuned approximately for -12 to -8 InHg helps maintain proper valve response across typical boost levels. Perfect for enthusiasts and performance tuners looking to both enhance sound and improve compressor surge control, the TS-0204-1303 combines robust construction with customizable fitment potential in many custom turbo setups.
