With this valve your engine will emit sound characteristic of turbo engines.

Made of injected aluminum with exclusive blue electrostatic painting for greater durability and a differentiated finish.

This Blow Off Valve is mounted between the OEM solenoid valve and the original Turbo, causing the unused charge to be released to atmosphere emitting the sound of turbine relief.

It doesn't need any modification or adjustment.
