Our valve springs provide the stability needed for high lift, high rpm racing engines, while minimizing the load loss for today€™s aggressive valvetrain combinations.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eControls Dominant Harmonics\u003c\/li\u003e\n\u003cli\u003eProvides Needed Stability\u003c\/li\u003e\n\u003cli\u003eReduce Valvetrain Component Wear\u003c\/li\u003e\n\u003cli\u003eDeveloped from High Strength Alloys\u003c\/li\u003e\n\u003cli\u003eHeat-Treated and Stress Relieved\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"newdescrLC\"\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e2009 - 2014 Acura TSX (K24Z3)\u003c\/li\u003e\n\u003cli\u003e2013 - 2015 Acura ILX (K24Z7)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat's In The Box?\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e16 - Dual Springs (S10164)\u003c\/li\u003e\n\u003cli\u003e16 - Titanium Retainers (E11141)\u003c\/li\u003e\n\u003cli\u003e16 - Seat Locators (SL1149)\u003c\/li\u003e\n\u003cli\u003e16 - Valve Locks (K10034)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWarranty\u003c\/h3\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eFerrea Manufacturer's Warranty\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"clear\"\u003e\u003c\/div\u003e","brand":"Ferrea Racing","offers":[{"title":"Default Title","offer_id":46667119171,"sku":"FER KT4005","price":1041.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0890\/6136\/files\/ferrea-racing-fer-kt4005-30338521923654.webp?v=1737395676"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0890\/6136\/collections\/ferrea.jpg?v=1563407354","url":"https:\/\/www.maperformance.com\/collections\/ferrea-racing\/in-stock.oembed?page=8","provider":"MAPerformance","version":"1.0","type":"link"}
