VW VR6 12V exhaust Valves FERREA Ferrea fer-12v-ex - сервиз

Exhaust valves from FERREA for VW VR6 12V 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 Ferrea valves are made from an extremely heat-resistant alloy. The Ferrea valves are suitable for engines with turbocharging and nitrous oxide injection where high exhaust temperatures are used. Available in original size and 1mm oversize. For 1mm oversize valves, the valve seat must be adapted. The kit contains 6 valves. Suitable single-wedge valve wedges are required! (see under accessories) Ferrea is also used in major racing series such as Formula 1, Indy, Nascar and drag racing.
