OE number: 17123852/17106809/17113578/17113625/17123855/17125483/213914/25319901/3857487/38574877/8171238520/88893282/BP2Y18911A/MBP2Y18911. This is just for reference, please check and confirm the OE carefully before purchasing.
These are needed when using a HHO System or a test pipe.They are also used to lean out your vechicle for better gas milage.
The extender has a 7/8 hex head which is the same size as most O2 sensors and it makes them easer to install not like the straight sided extenders.
Fits all standard size sensors with a 1/2 Inch diameter tip.The size of the extenders is M18 X 1.50mm.
They are very easy to install by unscrewing your O2 Sensor from your exhaust then screw your sensor into the extender,and then screw the two pieces back into your exhaust.
The function of the oil temperature sensor is to detect the oil temperature of the engine so that the engine can run normally.
Installation location: the valve body harness in the oil pan of the automatic transmission or fixed on the valve plate
Remarks:
(1). When the oil temperature is low: the lock-up clutch will not be locked when the high gear is not raised.
(2). Downshift when the oil temperature is high, the lock-up clutch is locked.
(3). When the oil temperature is lower than 60 degrees Celsius, adjust the main oil pressure to be lower than the normal value to prevent shift shock due to low oil temperature and high viscosity.
(4). When the oil temperature is lower than -30 degrees Celsius, the computer control will adjust the main oil pressure to the maximum value to prevent the oil temperature from being too low and the oil viscosity is too high to make the shift process too smooth.
