Ferrea GM ECOTEC 36.1mm 5.97mm 102.5mm 20 Deg S-Flo +1mm Competition Plus Intake Valve - Set of 8

Ferrea is well-known for making high-performance engine components, and these Competition Plus intake valves are a prime example. Designed for GM Ecotec engines, these valves are a +1mm oversized option, meaning they are 1mm larger in diameter than stock. This larger size can help improve airflow into the combustion chamber, which is crucial for engines that have been modified for more power. The S-Flo design also helps with airflow dynamics, and the 20-degree seat angle is a common specification for performance applications.

Each valve measures 36.1mm in diameter with a 5.97mm stem and a total length of 102.5mm. They are built to handle the increased stresses of performance engines. If you're rebuilding or modifying your Ecotec engine and looking for improved airflow and durability from your intake valves, this set of eight is a solid option.
