Overview

The Supertech Nitride Intake Valves are a set of 12 one-piece forged valves designed for high-performance applications. Constructed from an enhanced version of EV8 (21-4N) stainless steel, these valves offer superior strength and durability. They feature a black nitride finish for increased hardness while maintaining core ductility, and a "Superfinish" valve stem with reduced surface roughness to minimize friction and carbon buildup.

Each valve has a head diameter of 31.40mm and a stem diameter of 4.96mm, with a length of 106.7mm. They are hardened to a minimum of 52 HRC. It is important to note that these valves require the use of KPR-5.0 or 7S locks.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
