IAG Beehive Valve Spring And Titanium Retainer Set For Subaru EJ Engine

IAG’s Beehive Valve Spring And Titanium Retainer Set reduces valvetrain weight by up to 68 grams and delivers increased spring pressure, allowing you to run increased boost and RPM over stock. This valve spring and retainer set is engineered for compatibility with all Subaru EJ20 and EJ25 engines. The lightweight and durable design of this set make it the ideal upgrade for mild-aggressive street, road race and drag racing applications. Upgrading to titanium retainers offers significant performance advantages over steel options. Titanium retainers are much lighter, which increases efficiency and allows the engine to rev higher without losing control of the valvetrain.
