Ford Focus RS MK3 2.3L 16V Inlet valves FERREA

High-strength steel inlet valves from Ferrea for Focus RS. The Ford 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 of only 5.5 mm, there is not much material left to protect the valve! Ferrea valves offer the following advantages: High temperature resistance Strong tear resistance 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 1 mm 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.
