Supertech BMW N54 Turbo Sodium Filled Inconel Exhaust Valve - +0.5mm Oversize - Single

If you're rebuilding the top end of your BMW N54 engine, especially for boosted applications, paying close attention to your exhaust valves is crucial. These Supertech sodium-filled Inconel exhaust valves are built to handle the extreme heat and stress that turbos put on the engine's valvetrain. The +0.5mm oversize dimension means they are designed to replace worn or damaged stock valves, ensuring a proper seal and restoring lost compression.

Inconel is a superalloy known for its exceptional strength and resistance to high temperatures, making it ideal for exhaust valve applications where temperatures can soar. The sodium filling inside the valve stem acts as an internal coolant, absorbing heat from the valve head and transferring it down the stem to the guide, which helps keep valve temperatures in check. This is a single valve, so you'll need to order the correct quantity for your engine's needs.
