You don't need any additional components here. Simply install and have fun! Do not use Longlife oil. The fully synthetic Castrol Edge 10W-60 oil is better.
BAR-TEK® tips!
We recommend 102 octane fuel: More power for your engine because it knocks less! Your turbo should not be too old and your engine should be in good condition. The base must be right. Check the red pressure hose on the turbocharger. This often leaks due to the heat of the manifold.

The original clutch can't transfer this extra power, so you need a sports clutch. For the conversion to K04-015 turbocharger you have to install a racing cat and our upgrade air mass meter.
If you have already installed a sports cat, an intake hose and an upgrade charge intercooler, you can continue to use them. The sport catalytic converter is very important for the 1.8T engines in the Passat and Audi A4.

To drive this incredible power, you have to replace your connecting rods with H-beam connecting rods. A sports clutch kit is required to get the 320 PS on the road. For the exhaust you should use a 76 mm exhaust system.
Good 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: You should build the downpipe in 70 mm, as the Passat and Audi A4 have a very narrow body at the bottom of the axle beam. You should move the catalytic converter downwards. This will reduce the exhaust temperature and protect the turbocharger!
