Tial MV-R Wastegate 44mm Red w/ All Springs | 002951
A wastegate especially an external wastegate is used to find and achieve precious boost levels.

-Water cooling ports (not required to run) for those heavy duty applications, three bottom pressure ports and two top ports for boost controllers like the AMS-1000.
- High temp NiCrFe based alloy is used for valve and 347SS valve housing will offer longer product life compared to competing designs.
- High temperature silicone Nomex reinforced actuator diaphragm.
- 17-7 PH Stainless Steel actuator spring gives consistent pressure at high temperature, resist "relaxing" at temperature to 900F (483C).
- Nitronic 60 Stainless Steel is used for the valve seat, and valve bushing.

The Tial MV-R Wastegates now comes with all of the springs so you can tune it to your cars needs without spending money on extra springs.
