Supertech Performance VWIVN-1002T-8 Black Nitrided Intake Valve for Audi VW 2.0T FSI

These high-performance valves are designed to deliver superior flow, durability, and reliability for both street and racing applications.

Key Specifications:

• Head Diameter: 33.85mm (standard size)
• Stem Diameter: 5.98mm
• Overall Length: 103.9mm
• Material: One-piece forged stainless steel 21-4N (EV8)
• Coating: Black nitride surface treatment
• Groove Type: Triple groove valve lock design
• Includes valve keepers (collets) for installation

Black Nitride Advantages:

• Superior microhardness (minimum 800HV) for enhanced wear resistance
• Smoother surface finish reduces friction between stem and valve guide
• Harder valve seat surface for extended life with modern fuels including ethanol blends
• Compatible with all seat materials including nodular iron, powder metal, and aluminum-copper alloys
• Reduced internal engine friction for improved performance at high RPM

Supertech valves are manufactured using state-of-the-art quality control including ultrasonic testing, X-ray inspection, laser measurement, and Finite Element Analysis (FEA). Each valve is precision-forged from a single piece of enhanced EV8 stainless steel alloy, providing exceptional strength and reliability. The black nitride coating process creates a hardened surface layer while maintaining excellent ductility underneath, ensuring these valves can withstand the demands of high-performance turbocharged engines.

These valves are designed to fit standard valve seats and are compatible with engines found in Volkswagen, Audi, Seat, and Skoda vehicles equipped with 1.8L and 2.0L FSI/TSI/TFSI engines, as well as select 2.5L TFSI 5-cylinder applications including TTRS, RS3, and RSQ3 models with EA855 engines.
