Titanium construction makes these retainers significantly lighter than the factory steel pieces they replace, and that reduced reciprocating mass directly helps the valve springs control valve movement at higher RPM. Less valvetrain mass means a higher safe RPM ceiling before valve float becomes a real risk. It's a straightforward improvement that's easy to appreciate once it's installed.\u003c\/p\u003e\n\n\u003ch3\u003eA Full Set of 16 for Consistent Valvetrain Behavior\u003c\/h3\u003e\n\u003cp\u003eThis set includes all 16 retainers needed for a complete EJ20\/EJ25-based engine, keeping installed height and spring pressure consistent across every cylinder. That consistency matters for predictable valvetrain behavior rather than one cylinder behaving differently than the rest. It's the correct retainer choice specifically when paired with Manley's matching 22180-16 spring part number. That combination of durability and performance is what makes it worth the upgrade.\u003c\/p\u003e\n\n\u003ch3\u003eStraight From Subispeed\u003c\/h3\u003e\n\u003cp\u003eThe correctly matched titanium retainer set for 2002-2012 WRX \/ 2004-2012 STI when paired with Manley's 22180-16 springs — confirm your spring part number before ordering.\u003c\/p\u003e\n\n\u003cp\u003eThis Part Fits:\u003c\/p\u003e\u003ctable border=\"1\"\u003e\n\u003ctr\u003e\n\u003cth\u003eYear\u003c\/th\u003e\n\u003cth\u003eMake\u003c\/th\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2002-2012\u003c\/td\u003e\n\u003ctd\u003eSubaru\u003c\/td\u003e\n\u003ctd\u003eWRX\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2004-2012\u003c\/td\u003e\n\u003ctd\u003eSubaru\u003c\/td\u003e\n\u003ctd\u003eSTI\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Manley Performance","offers":[{"title":"Default Title","offer_id":53062413484321,"sku":"MAN23180-16","price":251.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/9029\/2257\/files\/group-7b533850-f021-4ec1-b80d-93a74c460d85-800.jpg?v=1784694882","url":"https:\/\/www.subispeed.com\/products\/manley-subaru-wrx-sti-1-050-755-16pc-titanium-retainers-for-use-with-22180-16-springs","provider":"SubiSpeed","version":"1.0","type":"link"}
