Wastegate spring for Audi external wastegates which came on Audi turbo cars from 1980-1995.5.
Gives 2.2 BAR absolute or 17.5psi boost pressure when installed in wastegate, perfect for increasing the base boost pressure and eliminating wastegate creep.
NOTE: will not function with most chipsets on the market with overboost cutoff's below 2.2BAR, recommended for use in custom tuned cars or running our 034EFI engine management systems.
