Show original supplier description
The IAG Single Valve Spring and Titanium Retainer Set is a performance upgrade for Subaru EJ20 and EJ25 engines. Constructed from lightweight titanium and durable chrome silicone alloy steel, this set is designed to reduce valvetrain weight by up to 153.6 grams while delivering increased spring pressure. This allows for higher RPM operation, with a recommended maximum of 8000 RPM for safe use. This set is compatible with a wide range of Subaru models, including the 2002-2014 WRX, 2004-2021 STI, 2004-2013 Forester XT, 2005-2012 Legacy GT, and 2005-2009 Outback XT. It can be used with OE camshafts or performance camshafts such as S1/S2 GSC cams or similar units. Please note that valve keepers/locks are not included with this set.
