Ferrea Fiat 178B/182A/M645TA15T 31.45mm 6.98mm 25 Deg S-Flo +1mm 6000 Series Int Valve - Set of 8

If you're rebuilding the top end of your Fiat 178B, 182A, or M645TA15T engine, new intake valves are a critical component. These Ferrea 6000 Series valves are designed to handle the demands of performance builds and offer a solid upgrade over stock components.

Each valve measures 31.45mm in diameter with a 6.98mm stem and features a 25-degree S-Flo profile. This updated design helps improve airflow into the combustion chamber, which can lead to better performance. The +1mm sizing means these valves are slightly larger than standard, allowing for increased flow when used with appropriately modified cylinder heads. They are constructed from Ferrea's 6000 Series material, known for its strength and durability under high temperatures and pressures.

This set includes eight intake valves, enough for a complete engine. Ensure your cylinder heads are prepared to accept the larger valve size for optimal performance.
