Introducing a 100% bolt-on, direct replacement wastegate actuator upgrade for the Mitsubishi TD04HL Straight Flange Turbos. Our wastegates are manufactured to withstand increased boost pressures in a reliable manner, using a stiffer actuator spring designed to open the wastegate flapper from 4 - 8 PSI, and can hold up to 25 PSI of sustained turbo boost pressure.
