Upgrade Wastegate Spring Audi 5 Cylinder – 9 kg Version

This upgrade wastegate spring is the ideal solution for the original wastegate of classic Audi 5-cylinder engines. With the 9 kg version, boost pressures up to approx. 4 bar absolute pressure can be achieved, making it a suitable and reliable solution for most conversions with the original wastegate.

This spring is recommended if you want to run a boost pressure beyond 2.5 bar. 

Especially for engines with increased performance, the stronger spring ensures more stable boost pressure control and supports clean, constant control behavior. For operation and especially when opening the wastegate, we also recommend using an upgrade diaphragm/new diaphragm to further optimize function and durability.
