Ferrea Subaru/Toyota FA20 Dual Valve Spring - Set of 16

This set includes 16 Ferrea dual valve springs, designed to replace the stock springs in your Subaru or Toyota FA20 engine. Valve springs are crucial for keeping your engine's valvetrain in sync, ensuring that valves open and close at the precise moments needed for optimal combustion and performance. When you're looking to upgrade your engine's capabilities, especially for higher RPMs or more aggressive camshaft profiles, a robust dual valve spring setup like this one from Ferrea is a key component.

Ferrea is known for making well-built valvetrain components, and these dual springs are no exception. They are engineered to handle the increased stress and higher rotational speeds that performance-oriented FA20 engines often encounter. The dual spring design offers better stability at high RPMs, helping to prevent valve float, which can lead to serious engine damage. This means your engine can safely rev higher and maintain its power band more effectively. The set comes with all 16 springs needed to service your engine's cylinder heads, making it a complete solution for your valvetrain upgrade.

When undertaking a project like this, it's important to have the right tools and knowledge for proper installation. Ensure you consult your vehicle's service manual or a trusted mechanic for the correct procedures, especially when dealing with valvetrain components. This set is a solid option for anyone looking to build a more powerful and reliable FA20 engine for track use or spirited driving.
