What retainers do I need for these valve springs?

These Manley valve springs (part number 22180-16) are designed to be used with Manley's 23180-16 retainers. These retainers are sold separately and are essential for proper installation and function.

What is valve float and how do these springs help prevent it?

Valve float occurs when the valve springs can't close the valves fast enough, especially at high engine speeds. This can cause the valvetrain to lose synchronization. These Manley springs are built with specific tensions and heights to ensure valves close quickly and reliably, preventing float.

Are these springs suitable for a stock engine?

While these springs are well-built and can be used in performance applications, they are designed with specific dimensions (1.050" installed, .755" open) that are often chosen for modified or performance-oriented Subaru engines. It's always best to consult with your engine builder or refer to specific build recommendations for your application.

About this part

Product Details

This set includes 16 Manley valve springs, specifically designed for your 2002-2012 Subaru Impreza or 2005-2006 Saab 9-2X. These springs are intended for use with Manley's 23180-16 retainers, which are sold separately. Proper valve springs are crucial for keeping your engine's valvetrain in sync, especially at higher RPMs, ensuring that valves close quickly and reliably.

Manley has a solid reputation for making well-built engine components, and these valve springs are no exception. They are built to handle the demands of performance-oriented Subaru engines. The specific dimensions, 1.050 inches installed height and .755 inches open height, are key specifications that help dictate how the spring performs under load. When paired with the correct retainers, these springs help prevent valve float, which can lead to serious engine damage.

If you're rebuilding the top end of your Subaru engine or looking to improve its performance, these Manley valve springs are a popular choice. Remember that these springs are designed to work with specific retainers (part number 23180-16), so make sure you have those on hand before you begin installation.
