Specification: The Auto Timer allows the vehicle to idle for a preset amount of time after the ignition key has been removed. 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._x000D_ _x000D_ Features:_x000D_ _x000D_ High useful turbo timer, helps to protect your turbo by cooling down after driving. _x000D_ Greatly improving the combustion efficiency of the engine, save a certain amount of fuel consumption. _x000D_ The voltage, oxygen content (O2) and air fuel ratio (A/F) can be displayed. _x000D_ This turbo timer has the unique feature of RPM monitor to automatically calculate idling times. _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. _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. _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. _x000D_ Compact size and light weight, convenient and space-saving for installation. _x000D_ Universal fit for all vehicles with a 12 volt switched power source. _x000D_ _x000D_ Specification:_x000D_ Condition: 100% brand new_x000D_ Material: plastic_x000D_ Shell Color: black_x000D_ LED Light Color: Blue_x000D_ Voltage: DC 12V_x000D_ Black Display Case Size: 6.4 * 5.1 * 2.6cm/2.5 * 2.0 * 1.0in_x000D_ Black Control Unit Case Size: 10 * 1.8 * 1.2cm/3.9 * 0.7 * 0.5in_x000D_ Package Weight: approx.144g/5.1oz_x000D_ Fitment: universal fit for all vehicles with a 12 volt switched power source_x000D_ _x000D_ Package list:_x000D_ 1 * Turbo Timer Device_x000D_ 1 * Relay Unit_x000D_ 3 * Cable Ties_x000D_ 2 * Double Sided Tape_x000D_ _x000D_ Notes:_x000D_ 1.
