Supertech BMW B48 29.5x5.95x100.1mm Sodium Filled Inconel Exhaust Valve - Single (Drop Ship Only)

This Supertech exhaust valve is made from Inconel, a strong nickel-chromium alloy known for its high-temperature strength and corrosion resistance, making it a solid choice for demanding engine conditions. It features a sodium-filled stem, a design that significantly improves heat transfer away from the valve face and into the cylinder head. This helps keep the valve cooler, which can lead to more consistent performance and potentially longer life under high heat loads, especially in performance-oriented BMW B48 engines.

The valve measures 29.5mm in diameter and 100.1mm in length, with a 5.95mm stem. These dimensions are critical for proper fitment and sealing within the valve guide and combustion chamber. Using Inconel and sodium filling addresses the extreme temperatures exhaust valves endure, helping to prevent warping or premature failure compared to standard materials.
