Audi B5 S4 JAE Tial Wastegate Actuators
These are a popular upgrade for the failing stock actuators and aftermarket actuators found on many turbos manufactured for the 2.7T. These will work on rs4 and rs6(2.7t fitment) turbos. These are built to order and will come with a 1 bar spring unless specifically noted in the order. These are built with 1pc arms so there is no worry of the arm snapping from cheap threaded rod being bent.
This diaphragm design allows for more misalignment then the mamba actuators without binding. misalignment will still cause drivability/surging issues as the actuators will likely not be balanced.
When purchased through us we offer support to ensure installation is correct.
