Ford Focus RS MK3 2.3L 16V Super Alloy exhaust valves FERREA Ferrea 21fo074 - сервиз

Super Alloy exhaust valves from Ferrea made of high-strength steel for Focus RS. The Ford standard valves have the major disadvantage that they can break on 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 of only 5.5 mm, there is not much material left to protect the valve! 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 gas temperatures are used. Ferrea valves offer the following advantages: High temperature resistance High tensile strength Heat-treated material High-strength steel Quality and workmanship at the highest level Available in original size or 1mm oversize The kit contains 8 valves For 1mm oversize valves, the valve seat must be adapted. 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. Ferrea is also used in major racing series such as Formula 1, Indy, Nascar and drag racing.
