1. Enhance the torque of the pressure relief valve to effectively protect 2. Protect turbine service life 3. Improve the turbine response and enhance the power supply response 4. The of this product is made of aluminum alloy material, which is moisture-proof and anti-corrosion. It is not a worn-out part. The service life is basically not a problem. What is important is that it creates a fascinating sound for pressure relief, which can be external or internal The conversion between leaking, internal and external leaking is also quite simple, and can correspond to engines with different boost values. 5. With the introduction of the Turbo Engine, we have developed a Patented Atmospheric Blow-Off adapter specifically designed to fit this application. 6. Simple in execution, yet offering the desirable atmospheric blow-off valve sound, this product has been designed to be fully compatible with for engine management systems employed.
