TiALSport springs are engineered for precise control under extreme conditions.
Manufactured from 17-7PH stainless steel, they provide consistent pressure at high temperature, and resist 'relaxing' at temperatures up to 900degF (483degC), well beyond the required temperatures of the actuator.
Springs are color-coded, and are sold individually.
Please see the specific diagram for your specific model, at
to correlate color coding and diameter in order to choose the correct item.
MVS and MVR Series springs have different ratings for each corresponding wastegate model.
