FERREA Super Alloy Exhaust Valves for 2.5 TFSI Engines
FERREA Super Alloy exhaust valves for all 2.5L TFSI engines, such as those found in Audi TT RS and Audi RS3 models.
The standard exhaust valves in Audi 2.5L TFSI engines have a significant weakness: they can fail in engines with significantly increased power or high mileage. The standard valves are hollow and sodium-cooled, and their very thin valve stem leaves little material to protect the valve.
Benefits of FERREA valves
- High heat resistance
- Excellent fracture strength
- Special heat-treated material
- Extremely strong construction
- Top-tier quality and finish
FERREA Super Alloy valves are made from a special alloy with extremely high heat resistance. They are particularly suitable for turbocharged engines and configurations equipped with nitrous oxide (NOS) systems, where exhaust gas temperatures are very high.
Additional information
- For +1 mm oversized valves, the valve seat must be machined to fit
- Package includes 10 valves
- FERREA components are used in Formula 1, IndyCar, NASCAR, and drag racing series, among others
Installation recommendation
For triple-groove valves, it is always recommended to use new OEM valve keepers. This ensures proper valve seating. Using worn keepers can cause play, preventing the valve from seating correctly.
