Duo-35 Polished BOV

This exclusive blow-off valve features a dual cross tunnel discharge system with various discharge designs. You can use one or two GT-K inspired horns to vent the pressurized air directly to atmosphere for that extra loud discharge. Without the horn, you can re-circulate for tuning purposes and quieter operation. Compressor surging is a problem no more! Turbonetics exclusive plenum design allows the valve to stay shut air-tight when it senses boost. The valve opens up without hesitation when the unit senses vacuum. This is the ultimate blow-off valve for your turbocharged setup!
