SKU: S00P SIVN-1010-8
Moderate — 2–4 hours
Description
These valves are made from one-piece forged stainless steel and undergo a special hardening process to reduce friction between the valve and guide, which can help decrease internal engine friction and power loss at higher RPMs. The black nitride treatment offers a smoother surface finish compared to chrome plating.
