Supertech BMW N54B30A Sodium Filled Inconel Exhaust Valve - Single (Drop Ship Only) (Use w/Locks)

This is a single Supertech sodium-filled Inconel exhaust valve, specifically made for the BMW N54B30A engine. If you're rebuilding the top end of your N54, especially if you're pushing more power or dealing with high exhaust temperatures, these valves are a solid choice. The Inconel material is known for its excellent resistance to extreme heat and corrosion, which is crucial for exhaust valves that face the brunt of combustion gases.

What makes these valves stand out is the sodium filling. This advanced feature helps to dissipate heat away from the valve face and stem more effectively than a solid valve. As the sodium inside melts and vaporizes, it moves up into the hollow stem, transferring heat to the valve guide. This improved cooling helps prevent valve distortion and extends the life of the valve in demanding conditions. They are designed to be used with your existing valve locks.
