1.8T 20V Super Alloy exhaust Valves FERREA Ferrea fer-18t-ex - сервиз

Super Alloy exhaust valves from FERREA for all 1.8T engines. The VAG 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 a very thin valve stem of only 6 mm, 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 Super Alloy valves from Ferrea are made from an extremely heat-resistant alloy. The Ferrea Super Alloy valves are suitable for engines with turbocharging and nitrous oxide injection where high exhaust temperatures are used. With 1mm oversize valves, the valve seat must be adapted. The kit contains 8 valves. Ferrea is also used in major racing series such as Formula 1, Indy, Nascar and drag racing. We run this Ferrea valve kit successfully in our 1.8T test Golf. 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 clogged, the valve will not seat correctly and will have play.
