1Function: Turbo timer is designed to keep the car engine running for a pre specified period of time in order to automatically perform the required cooling down to prevent premature turbine wear and failure. 2Programmable: The turbo timer can be programmed to keep the engine running for a pre specified period of time even after the driver gets out of the car and locks the vehicle. 3Optimize Engine Operation: The car turbine timer can control the turbine to optimize engine operation, improve engine efficiency, increase power output, and make your car smoother. 4Delays The Cooling Down: The timer delays the cooling down of the turbine after the engine is turned off. This allows for a smooth transition of the thermal cycle, protecting the turbine and engine from excessive wear, while extending engine life. 5Universal Fit: Turbo flameout delay protector is universal for cars, LED digital display, professional manufacturing, high performance, strong reliability, making sure safety use.
