In turbocharged vehicles this prevents hot oil in the engine from coking up in the lines. Hard driving can raise engine oil temperature to dangerously high level. Proper cool down is essential for a healthy turbo and engine. In normally aspirated cars, the Auto Timer can also be used to warm/cool the inside of the car without having to sit inside._x005f_x000D__x005f_x000D_Features:_x005f_x000D__x005f_x000D_High useful turbo timer, helps to protect your turbo by cooling down after driving. _x005f_x000D_Greatly improving the combustion efficiency of the engine, save a certain amount of fuel consumption. _x005f_x000D_The voltage, oxygen content (O2) and air fuel ratio (A/F) can be displayed. _x005f_x000D_This turbo timer has the unique feature of RPM monitor to automatically calculate idling times. _x005f_x000D_Automatic countdown feature in order to ensure the most optimum countdown setting from the widest array of vehicles the user can choose from 144 different setings. _x005f_x000D_First timer to utilize O2 sensor voltage when calculating count down time compared to timers that only use vehicle speed and RPM,this timer can set the most accurate after idling time possible. _x005f_x000D_This Turbo Device is equipped with a parking Brake safety function which will keep the car from moving forward when idling in the count down function. _x005f_x000D_Compact size and light weight, convenient and space-saving for installation. _x005f_x000D_Universal fit for all vehicles with a 12 volt switched power source. _x005f_x000D__x005f_x000D_Specification:_x005f_x000D_Condition: 100% brand new_x005f_x000D_Material: plastic_x005f_x000D_Shell Color: black_x005f_x000D_LED Light Color: Blue_x005f_x000D_Voltage: DC 12V_x005f_x000D_Black Display Case Size: 6.4 * 5.1 * 2.6cm/2.5 * 2.0 * 1.0in_x005f_x000D_Black Control Unit Case Size: 10 * 1.8 * 1.2cm/3.9 * 0.7 * 0.5in_x005f_x000D_Package Weight: approx.144g/5.1oz_x005f_x000D_Fitment: universal fit for all vehicles with a 12 volt switched power source_x005f_x000D__x005f_x000D_Package list:_x005f_x000D_1 * Turbo Timer Device_x005f_x000D_1 * Relay Unit_x005f_x000D_3 * Cable Ties_x005f_x000D_2 * Double Sided Tape_x005f_x000D__x005f_x000D_Notes:_x005f_x000D_1.
