Description

The Supertech HEVN-1007-8 is a set of 8 stainless steel black nitride exhaust valves designed for Honda H22A VTEC engines. These valves feature an oversize +0.5mm head diameter and are constructed from durable stainless steel 23-8N.

The black nitride surface treatment reduces friction and wear between the valve and guide, contributing to smoother operation and reduced power loss at higher engine speeds.
