2.5 TFSI Audi RS3 & TTRS Inlet valves FERREA Ferrea 21rs376 - сервиз

Intake valves from FERREA made of high-strength steel for all 2.5L TFSI engines as installed in the Audi TTRS and RS3. The standard valves of the Audi 2.5L TFSI engine 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 Strong tear resistance Special heat-treated material High-strength material Quality and workmanship at the highest level Available in original size or with 1mm oversize. The valve seat must be adapted for 1mm oversize valves. 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 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.
