Hello.

There are a number of conditions:
1. Your car must be equipped with a turbocharged engine.
2. You must be Piwis Tester and the ability to use it.
3. You must strictly follow the instructions.
4. When ordering, be sure to specify the VIN (chassis number) of your car.

I'm willing to make allowances 300 USD, if you write a detailed review on this forum. When ordering, you will need to enter the word "turbo_kit", to get a discount of 300 USD.
