FERREA Reinforced Intake Valves for 2.5 TFSI Engines
FERREA intake valves are made of high-strength steel for all 2.5L TFSI engines, including those used in Audi TT RS and Audi RS3 models.
Standard valves in the Audi 2.5L TFSI engine have a significant weakness: they can fail in engines with significantly increased power or high mileage. Standard valves are hollow and sodium-cooled, and their thin valve stem leaves little material to protect the valve.
Benefits of FERREA Valves
- High heat resistance
- Excellent fracture strength
- Specially heat-treated material
- Extremely strong construction
- Top-tier manufacturing quality
Available in standard or +1 mm oversized versions.
Note: For +1 mm valves, the valve seat must be machined to fit.
Additional Information
- Package includes 10 valves
- FERREA components are used in Formula 1, IndyCar, NASCAR, and drag racing series, among others.
Installation Recommendation
When installing new Dreinut valves, it is always recommended to use new OEM valve cotters. This ensures proper valve seating. Worn cotters can cause play, preventing the valve from seating correctly.
