Mitsubishi Sodium Filled Exhaust Valves Evo 8

These are OEM exhaust valves from the Lancer Evolution 8. They are filled with sodium which allows a much greater heat dissipation over solid valves while saving some weight. These will drop right into your DSM 4G63 head. Sold as a set of eight. Original equipment on all 2003-2007 Mitsubishi Lancer Evolution, and can be retrofitted into all 1990-1999 DSM (Eclipse/Talon/Laser) cars.
