Product Details
With an installed height of 1.126 inches and a .640-inch lift capacity, these Manley valve springs are built for Subaru EJ20 and EJ25 engines found in the Impreza. They are specifically designed to work with Manley's 23185-16 retainers, ensuring a matched set for optimal performance when you're rebuilding or upgrading your engine's top end.
These springs are a well-built component for enthusiasts looking to get the most out of their Subaru's engine. They are designed to handle increased camshaft lift and duration, which is common in performance applications. The materials and construction are chosen to maintain consistent valve control under demanding conditions, helping to prevent valve float at higher RPMs.
When installing these valve springs, remember they are intended for use with the matching Manley retainers. This pairing is crucial for achieving the correct spring pressure and ensuring the longevity of your engine's valvetrain components. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
