Supertech Performance HIVN-1050-8 High-Performance Intake Valves

Supertech Performance is a globally recognized manufacturer of precision engine components trusted by professional race teams and performance enthusiasts alike.

These valves feature a black nitriding surface treatment, a thermochemical process that dramatically improves surface hardness, wear resistance, and corrosion protection without affecting the base material's core properties. The result is a valve that withstands extreme heat cycles and high-RPM operation far beyond the limits of standard OEM valves.

Key Features:

• Black nitride (ferritic nitrocarburizing) coating for superior surface hardness and wear resistance
• Precision-machined from high-grade one-piece stainless steel or silicon-chromium alloy (model dependent)
• Tight dimensional tolerances for optimal sealing and valve-to-seat contact
• Compatible with upgraded valve springs and high-lift camshafts
• Designed for high-RPM performance engines in motorsport, track, and modified street applications
• Manufactured to meet or exceed OEM dimensional specifications

Supertech Performance valves are a direct upgrade for builds requiring improved durability and flow characteristics over stock components. The HIVN-1050-8 is ideal for engine builders seeking a reliable, race-proven valve solution for 8-valve or split-set applications.
