Supertech VW 2.0L TFSI 16V 28x5.96x101.8mm Sodium Filled Inconel Exhaust Valve - Single (D/S Only)

This Supertech exhaust valve is made from Inconel, a high-nickel, high-chromium alloy known for its exceptional strength and resistance to extreme heat. Specifically, this valve measures 28mm in diameter, has a 5.96mm stem, and a total length of 101.8mm. The Inconel material is crucial for exhaust valves because it can withstand the intense temperatures and pressures found in the combustion chamber, especially in performance-oriented engines like the VW 2.0L TFSI 16V. This helps prevent valve distortion or failure under demanding conditions.

A notable feature of this particular valve is its sodium-filled stem. The stem is hollow and filled with sodium, a metal that melts at relatively low temperatures. As the engine runs and the valve heats up, the sodium inside melts and circulates, absorbing heat from the valve head and stem and transferring it to the valve guide. This active cooling process significantly improves heat dissipation, allowing the valve to operate at lower temperatures. This is particularly beneficial for engines that see frequent high-RPM use or are tuned for increased power, as it helps maintain valve integrity and consistent performance over time. The valve is designed as a single unit, specifically for the exhaust side (D/S Only).

When rebuilding or upgrading the cylinder head on your VW 2.0L TFSI 16V, using valves made from advanced materials like Inconel with features like sodium filling is a smart choice for reliability and performance. This ensures that your engine's valvetrain can handle the stresses of operation, especially if you're pushing the limits of the stock components or have made modifications. Always ensure you are replacing valves in sets or as recommended by your engine build plan to maintain proper balance and function within the cylinder head.
