Description

The Supertech MAIVN-1206-8 is a set of eight +1mm oversize black nitride intake valves designed for the 1994-1997 Mazda MX-5 Miata. These valves are constructed from an enhanced EV8 (21-4N) stainless steel for superior strength and durability.

The black nitride coating provides enhanced hardness, superior wear resistance, and reduced friction, while the "Superfinish" valve stem further minimizes friction and improves sealing. Features include a one-piece forged valve design, a magnetic friction-welded wafer hardened to 52 HRC minimum, and an undercut stem for reduced weight and improved airflow.
