Supertech intake valves are made exclusively from an enhanced version of EV8 (21-4N) steel. This is the highest grade of steel available and provides the strength to withstand just about any application. Some applications call for us to harden certain areas such as the tips and or the seats. For these applications we will often times weld other hard metal alloys to the valve for increased durability.
The 10th Gen Civic Type R valves feature a black nitride coating as well. This is a hardening treatment that has been steadily growing in popularity over the last several years. These black Nitride coated valves feature harder surfaces and smoother finishes, providing less friction and subsequently longer life.
