Supertech Valves and Valve Springs Upgrade Kit For 2.5T EA855/EA855 EVO RS3 8P/8V TTRS MK2/MK3

Black nitride intake valves from Supertech for all 2.5L TFSI engines

The standard VAG valves have the major disadvantage that they can break on engines with significant power increases or long mileage.
The standard valves are hollow inside and sodium-cooled. With the very thin valve stem of only 6mm, there is not much material left to protect the valve!

The kit from Supertech offers the following advantages:

• High-temperature resistance
• Strong tear resistance
• Nitride material
• Extreme Flow Valves outperform any other valve on the market today, and with their Nitride Coating are perfect for High Temperatures (and run cooler which improves value life), Nitrous, Turbos, and Superchargers. For naturally aspirated motors these valves will give you a much greater cylinder flow for good HP gains.
