Just because electric car manufacturers are trying to make automobiles whisper quiet doesn't mean the rest of us have to suffer in silence. Half the fun of driving is listening to the roar of the engine, the bark of the exhaust and the whip crack of the BOV. Go ahead-turn your turbo's volume up to 11 with the Turbosmart Supersonic Blow Off Valve.
If you're aiming for stealth, the Turbosmart Supersonic is not the BOV for you. It's the loudest atmospheric blow off valve that Turbosmart makes. When it opens its mouth, it screams like a high-octane banshee. Whether you're hot lapping at the track or revving up at a car show, all ears will be fixed on your speed fiend.
More than just a loudmouth, the Turbosmart Supersonic Blow Off Valve boasts wicked-fast flow for faster spooling and dramatically lowered lag times. You can dial in the settings in a flash with its rotating cap and positive-seal piston-all with no tools needed. Plus, they're carved from tough billet aluminum and come in your choice of rich colors. 1-year warranty.
