Subaru EJ Models (inc. 2002-2014 WRX / 2004+ STI)
Product Resources
Features & Product Details
The Manley Performance Valve Spring and Retainer Kit has been designed to accommodate high-lift cams, and to allow users to surpass OEM rev limitations when power levels have been increased from built motors, larger turbochargers, aggressive cams, or ported heads. Basically if you plan on drag racing, time trials, or any form of spirited driving where the engine lives in the upper- RPM range then upgraded valve springs are a must.
The Manley Performance Valve Springs and Retainers are fabricated from high grade steel and titanium respectfully, and the max net lift is 0.525”

Have had great luck with these springs great quality. Put them in my 2006 Wrx heads and work amazing. Don’t have to worry about valve float anymore under high boost like you do with OEM valves and springs.
