Hose inside diameter is 76mm (3"), much larger than original for increased airflow. 80mm connection to the MAF (original) Developed for 70mm connection on turbo! But mounting accessories to mount on original 60mm turbo connection are included. Socket for BOV recirculation (25mm) is located on the hose underside. This is for those who do not use the original by-pass valve in the turbocharger. Plug is included if this is not used. Note that the hose is designed for 70mm turbo connection. This means that it is very little space to install this hose for cars with OEM turbo with 60mm connection. The hose is very tight against the wastegate bracket and coolant to the turbo. But it is possible to mount (not for the amateur)! The hose is reinforced with steel wire so it won’t collapse during high vacuum.This hose kit is available in three different colors Blue / Black / Red. There are no performance difference between the different colors, choose which color you think will be best for your car.
