Description

Supertech INCONEL exhaust valves from Supertech for all G4KF engines, such as in the Hyundai i30N and Veloster.

The standard valves have the major disadvantage that they can break on engines with significant power increase or long mileage. The standard valves are hollow inside and sodium cooled. With the very thin valve stem of only 6mm there is not much material left to protect the valve!

The valves from Supertech offer the following advantages:

  • High temperature resistance
  • Strong tear resistance
  • INCONEL material

Higher flow rates:
Supertech valves are specifically designed for each application to achieve the best possible result. Constant efforts are made to further improve the design through continuous development, testing and inspection.

Durability:
In every valve design, Supertech takes care to maximize durability and tensile strength through higher fatigue resistance. Each valve has a hardness rating above 52HRc.

Nitride Black:
A hardness treatment that is not as well known as chrome plating, but has significant advantages over it. The micro hardness is higher than the basic coating because the ductility is changed by the nitrided layer (micro hardness 800Hv minimum). The valve surface is smoother than chrome plated and therefore there is less friction between the valve and the valve guide. The valve seat surface is more resistant to unleaded fuels, alcohol, nitro or other "explosive" mixtures due to the nitrided layer.
Available for any type of valve seat (ductile iron, metal powder mix, hard aluminum-copper mix or beryllium-copper mix). The nitride coating reduces power loss at high speeds by reducing friction in the valve guide. Compared to the chrome coating, which is applied only on the stem, the Nitride Black coating is on the whole valve. All valves are vortex polished and have a hardened tip.

The kit includes 8 valves without valve wedges.
