You don't need any additional components here. Simply install and have fun! Do not use Longlife oil, our GTX Racing Oil 10W-60 oil is better.
We recommend filling up with 102 octane fuel. This will give your engine more power because it knocks less! The turbocharger should not be too old. Engine in good condition. The basis must be right.

To bring the extra power to the road, you need a sports clutch, because the original clutch cannot transfer the power. For the conversion to K04-01 upgrade turbocharger you have to install a racing cat and our upgrade air mass meter. A downpipe is a must.
If you have already installed a sports cat, an intake hose and an upgrade intercooler, you can continue to use them. With an upgrade intercooler you also have the complete performance available in summer! If you want to get 220 hp right away, order the tuning kit level 3 directly! That saves money.

To drive the full 320 hp power, you have to replace your connecting rods with X-beam connecting rods. A sports clutch kit is required to get the horsepower on the road. For the exhaust you should use a 76 mm exhaust system. The pump must be an upgrade, otherwise there is a risk of engine damage due to slimming.
A proper chip tuning is required for this conversion. You can send us your control unit or have your vehicle tuned directly in our workshop. Another tip from us: Your brake system is no longer up to the high performance. You can convert it to a Brembo 4-piston brake or to the Audi S3 8L.
