Supertech Mazda FS Protege 2.0L 28.60x5.96x89.95mm Dish Blk Nitrided Exhaust Valve - Set of 8

These Supertech exhaust valves feature a 28.60mm head diameter, a 5.96mm stem, and a length of 89.95mm, with a dish-shaped face. The black nitrided surface treatment is a key detail, as it hardens the valve face and stem, making it more resistant to wear and heat. This is important for exhaust valves, which operate under high temperatures and pressures as they control the flow of burnt gases out of the combustion chamber.

Built for the Mazda FS 2.0L engine, this set includes all eight exhaust valves needed for a complete engine rebuild or repair. The nitriding process not only improves durability but also helps to reduce friction, contributing to smoother operation and potentially better sealing. This well-built set is designed to handle the demands of the FS engine, offering a solid option for restoring or enhancing your engine's performance.
