Keep your TiAL external wastegate performing at its best with a genuine replacement spring, designed for precise boost control under extreme conditions. These springs are crafted from 17-7PH stainless steel to resist fatigue and maintain accurate pressure at temperatures up to 900°F (483°C).
Each spring is color-coded and sold individually, with pressure ratings that vary depending on your wastegate model. For higher boost levels, small and large springs can be nested together. Always reference the official TiAL spring chart to determine the correct combination for your desired base pressure.
