2.5L TFSI Audi RS3 & TTRS High Boost Nimonic exhaust Valves BAR-TEK®

With our many years of experience in motorsport and tuning, we can now proudly offer you our exclusively developed high-performance valves.

Our ambition was to develop specifically for the T(F)SI engine, a perfect valve that can easily withstand any performance. As a full valve, in combination with Nimonic and friction welded X45, we improve the temperature resistance enormously. 

Our valves offer the following advantages:

• High temperature resistance
• Strong tear resistance
• High strength Nimonic material
• X45 Friction welded
• Full valve
• only 44g per valve
• Nitrided
• 3 wedge groove for optimal grip
• Quality and workmanship at the highest level

The valves have standard dimensions. Kit Contains of 10 Valves.

The VAG standard valves have the major disadvantage that they can break on engines with significant power increase or long mileage.
The standard valves are hollow inside and sodium cooled. With the very thin valve stem of only 6mm, there is not much material left to protect the valve!

When installing a new Dreinut valve, we always recommend installing new OEM valve wedges. This will ensure that the valve is seated properly. If used wedges are used, they may have occlusion, the valve will not seat properly and will have play.
