These TiAL Wastegate Springs are for use in TiAL's F38, F40, F41, V44, F46, and V60 wastegates. Please see the information below to decide which spring(s) you may need. Higher Pressure Settings require the use of both small and large diameter springs. When using a dual spring setup the resultant pressure is equal to the sum of the individual springs.
Please Note: TiAL's MV-S wastegate requires the use of springs specific to that wastegate, these springs will not work for an MV-S application.
