Supertech Performance GIVN-3320S Black Nitrided Intake Valve

The Supertech Performance GIVN-3320S is a black nitrided intake valve (racing intake valve, engine intake valve) for performance engine builds. It is forged from a single piece of material and machined to precise dimensions.

Key Features:

• Black nitride hardening treatment on the valve
• Single groove design

Supertech forges these intake valves in a two-step process for grain flow and strength. They are CNC machined in multiple stages, then heat treated for stress relief before the nitride hardening step. The nitrided layer gives a hard working surface, and the surface is finished by precision grinding and Supertech's Superfinishing process.
