This makes for an excellent upgrade over the stock blow off valve to hold more boost and to have a quicker response.
Here are the key features:
Patented adjustable venting bias system found in the Stealth FX system
Allows you to control the amount of air that is vented to the atmosphere, or recirculated back into the intake to control the venting sound based on driver preference
You can achieve a vented blow-off valve sound without triggering a check engine light or other problems such as running rich or stalling
New hardware and tool will be provided to make this blow-off valve ready for the installation
