Inlet Valves by Ferrea made of very tough steel for all 2.5L TFSI engines as used in Audi TTRS and RS3.
VAG OEM-valves have the big disadvantage that they can easily break because inner hole for the natrium cooling.
The valves from Supertech have the following advantages:
The Ferrea Super Alloy are suitable for engines with turbocharged and nitrous oxide injection where high exhaust gas temperatures can be reached.
At 1mm oversize valves, the valve seat must be adjusted.
The kit includes 10 valves.
Ferrea is also used in major racing series such as Formula 1, Indy, Nascar and drag racing.
When installing a new triple groove valve, we always suggest to install new OEM valve keepers. This will insure that the valve locks intall properly in the valve and retainer. If you install used triple groove keepers they may have low and high spots that do not grip the groove of the valve correctly
