The reduction is used for connection of the oil cooler to the original oil circuit.
There is a rubber sealing and optional adapter for mounting to the engine block included in the package. On the sides there are also two outlets for sensors (i.e. for oil pressure and temperature with the 1/8" NPT thread).
The adapter is mounted between the engine block and the oil filter. Options: 3/4-16UNF, M18 x 1.5, M20 x 1.5, M22 1.5.
Before ordering, please select the type of center adapter for engine block attachment! If you did not find your car on the list, or you are not sure about the right choice, write the brand, model and the engine type of your car in the note to get the correct thread.
