These Ferrea 5000 Series intake valves are engineered for performance street and entry-level racing builds where durability and improved flow are critical. Featuring the Ferrea S-Flo (Super-Flo) design with a 25-degree back angle, these valves optimize airflow velocity through the intake port compared to standard profiles. Each valve is forged from high-tensile strength alloys specifically chosen to withstand the thermal and mechanical stresses of high-RPM VTEC operation.

This set provides a reliable upgrade over worn OE components, utilizing a stock-size flat head design to maintain combustion chamber volume while providing the superior material properties Ferrea is known for.
