Ferrea Competition Plus intake valves upgrade the Nissan RB26DETT with a full set of 12 oversize valves forged from EV8 aerospace-grade alloy. Each valve carries a 35.6mm head, a +1mm oversize over the roughly 34.6mm stock intake valve, on a 5.98mm stem measuring 102.33mm overall, with a 20-degree seat angle and an S-Flo undercut that smooths airflow into the port. Avionics-quality hard chrome on the stem and a specially hardened tip give the durability needed for high-rpm, high-boost turbo use.
