Supertech Subaru EJ20/EJ25 Sodium Filled Inconel Exhaust Valve - Single (Drop Ship Only)

Made from Inconel, a high-nickel alloy, this Supertech exhaust valve is built to handle the extreme heat found in Subaru EJ20 and EJ25 engines. The sodium-filled stem helps to transfer heat away from the valve face and into the cylinder head more efficiently, which can help keep valve temperatures down under demanding conditions. This is a single exhaust valve, intended as a replacement part for your engine rebuild or repair.

When you're rebuilding the top end of your EJ engine, especially if it's going to see higher performance use, using valves designed for heat resistance is key. Inconel is known for its strength and ability to resist warping and oxidation at very high temperatures, making it a solid choice for exhaust valves. The sodium filling inside the stem is a trick used in performance applications to improve heat dissipation, helping to ensure the valve stays cooler and functions properly.
