Ferrea Chevrolet LS1 2.055in 0.3135in 4.9in 12 Deg S-Flo Rad Grv 6000 Series Intake Valve - Set of 8

These Ferrea 6000 Series intake valves are made from a high-strength, high-temperature alloy, specifically chosen for demanding LS1 engine builds. Each valve measures 2.055 inches in diameter and has a 0.3135-inch stem, with an overall length of 4.9 inches. The 12-degree swirl-flow (S-Flo) radial groove design helps improve airflow into the combustion chamber, which can lead to better performance.

Ferrea uses a specialized heat treatment process for these valves to ensure they can withstand the intense heat and pressure found in performance LS1 engines. The material is also designed to resist valve float at higher RPMs. This set includes eight intake valves, enough for a complete set on a V8 engine.
