2.5 TFSI EA855 High Boost Nimonic exhaust Valves BAR-TEK® BAR-TEK Motorsport 21rs490 - сервиз

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 a perfect valve especially for the T(F)SI engine 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 optimum hold Quality and workmanship at the highest level The valves have standard dimensions. The kit contains 10 valves. The VAG standard valves have the major disadvantage that they can break in engines with a significant increase in performance or with long mileage.The standard valves are hollow inside and sodium-cooled. With the very thin valve stem of only 6 mm, there is not much material left to protect the valve! When installing a new Dreinut valve, we always recommend installing new OEM valve keys. This ensures that the valve is properly seated. If used wedges are used, they may have clogged, the valve will not seat correctly and will have play.Pictures show 8 valves, the kit contains 10 valves!
