The TiAL Sport MV-S External Wastegate is much more compact than its F38 predecessor, standing only 3.7” in height.

Features integrated AN4 water cooling ports that cycle a small amount of coolant through the actuator top to keep the temperatures down in extreme conditions such as road racing. These are leak tested after installation from the factory and can be removed if not utilized.

The V-Band flanges make installation pain free, the three lower & two upper air ports make connecting pressure sources and boost controllers easy!

Available in Black, Blue, Red, Chrome or Purple.
