What is the purpose of an external wastegate?

An external wastegate controls the maximum boost pressure your turbocharger can produce. It does this by diverting excess exhaust gas away from the turbine wheel, preventing it from spinning too fast and over-boosting your engine.

What does the .3 Bar spring mean?

The .3 Bar (4.35 PSI) spring determines the base boost pressure the wastegate will target. If you need higher boost, you can swap this spring for a different one or use a boost controller in conjunction with the wastegate.

Can I install this on my car in California?

No, this wastegate is not CARB approved and cannot be legally shipped to or installed on vehicles in California.
