Over years of thermal cycling, engine vibrations, and sustained cooling system pressure, the factory plastic becomes brittle. This results in stress cracks around the upper inlet neck, seam separation at the crimp joints, and catastrophic coolant loss under aggressive driving or high-ambient operating conditions.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered as a direct bolt-in upgrade, this all-aluminum radiator replaces fragile plastic tanks with precision TIG-welded aircraft-grade aluminum end tanks. The brazed core features an optimized fin density and multi-louvered design, increasing fluid contact surface area and significantly improving heat transfer efficiency. By eliminating glued seams and crimped plastic joints, this radiator maintains consistent hydraulic pressure integrity and resists heat soak under severe track or street conditions.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e2006-2015 Lexus IS (2.5L, 3.5L)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e4GR-FSE, 2GR-FSE \/ XE20, XE30 (GSE20\/GSE21\/GSE25\/GSE30)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e204-306 hp \/ 185-277 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e16400-31440 \/ DPI 2968\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2006-2015 Lexus IS250 2.5L V6 (RWD \/ AWD)\u003c\/li\u003e\n  \u003cli\u003e2006-2015 Lexus IS350 3.5L V6 (RWD \/ AWD)\u003c\/li\u003e\n  \u003cli\u003e2010-2015 Lexus IS250C \/ IS350C Convertible\u003c\/li\u003e\n  \u003cli\u003eDoes not fit IS F 5.0L V8\u003c\/li\u003e\n  \u003cli\u003eDoes not fit 2001-2005 IS300 (XE10)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Lexus Performance Standard\u003c\/h3\u003e\n\u003cp\u003ePreserve the high-revving output of your GR-series V6 engine with track-ready thermal management that bolts directly into factory mounting points while utilizing stock fan shrouds and plumbing.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50414492778744,"sku":"DS-ECLWQRMDS","price":209.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-radiator-for-lexus-is-2006-2015-2-5l-3-5l-1.jpg?v=1788307169","url":"https:\/\/performancechiptuning.com\/es\/products\/performance-radiator-for-lexus-is-2006-2015-2-5l-3-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
