Inconel exhaust valves from Supertech for all 2.5L TFSI Audi engines, like in the RS3 and TT RS.
The VAG standard valves have the big disadvantage that they can break on engines with significant power increase or long mileage.
The stock valves are hollow inside and sodium cooled. With the very thin valve stem there is not much material left to protect the valve!
Supertech valves offer the following advantages:
Inconel is a very strong metal alloy and is used in Formula 1 engines.
Available in original size or 1mm and 2mm oversize.
For 1 mm and 2 mm oversize valves the valve seat must be adjusted.
The kit contains 10 valves without valve wedges. Matching Supertech wedges are required. You can find them below under accessories.
