2.5 TFSI Audi RS3 & TTRS Exhaust valves FERREA Ferrea 21rs339 - сервиз

Super Alloy exhaust valves from FERREA for all 2.5L TFSI engines as installed in the Audi TTRS and RS3. The Audi 2.5L TFSI standard valves have the major disadvantage that they can break in engines with a significant increase in power or with long mileage. The standard valves are hollow inside and sodium-cooled. With the very thin valve stem, there is not much material left to protect the valve! FERREA valves offer the following advantages: High temperature resistance High tear resistance Special heat-treated material High-strength material Quality and workmanship at the highest level Super Alloy valves from Ferrea are made from an extremely heat-resistant alloy. Ferrea Super Alloy valves are suitable for engines with turbocharging and nitrous oxide injection where high exhaust gas temperatures are used. For 1 mm oversize valves, the valve seat insert must be adapted. The kit contains 10 valves. Ferrea is also used in major racing series such as Formula 1, Indy, Nascar and drag racing. When installing a new three groove 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 wear, the valve will not seat correctly and will have play.
