Factory radiators utilize crimped plastic end-tanks bonded to an aluminum core via rubber gaskets. Over repeated heat cycles, these plastic tanks become brittle, hairline-fracture near the inlet\/outlet necks, or suffer gasket separation under 15+ PSI cooling system pressures. Additionally, the stock core density restricts heat dissipation during continuous boost events, leading to elevated coolant temperatures and reduced power output via ECU thermal throttling.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis heavy-duty crossflow radiator eliminates plastic weak points with 2 mm aircraft-grade aluminum end-tanks fully TIG-welded to a vacuum-brazed 4-row core. Featuring 3\/8-inch tube spacing and 14–16 fins per inch (FPI), it dramatically increases total surface area and fluid capacity for superior heat dissipation. An integrated internal transmission oil cooler matches OE fluid line routing, ensuring stable transmission temperatures without requiring auxiliary cooler fabrication.\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;\"\u003e2006-2009 Jaguar XJR 4.2L Automatic\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;\"\u003eAJ34S Supercharged \/ X350, X358\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;\"\u003e400 hp \/ 413 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number \/ Cross-Ref\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eDPI 13148, CU 13148, 3W4Z8005AA, 5W4Z8005AA, 6W4Z8005AA, XW4Z8005BA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2006 Jaguar XJR Base Sedan 4.2L V8 Supercharged (Automatic)\u003c\/li\u003e\n  \u003cli\u003e2007 Jaguar XJR Base Sedan 4.2L V8 Supercharged (Automatic)\u003c\/li\u003e\n  \u003cli\u003e2008 Jaguar XJR Base Sedan 4.2L V8 Supercharged (Automatic)\u003c\/li\u003e\n  \u003cli\u003e2009 Jaguar XJR Base Sedan 4.2L V8 Supercharged (Automatic)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Jaguar Precision Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to exact OEM mounting dimensions, this cooling assembly drops cleanly into the factory X350\/X358 front clip with zero bracket modification, preserving stock fan shroud geometry, AC condenser clearance, and factory sensor integrity without triggering fault codes.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50416631513336,"sku":"DS-EDPL0LUXI","price":329.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-radiator-for-jaguar-xjr-2006-2009-4-2l-automatic-1.jpg?v=1788323186","url":"https:\/\/performancechiptuning.com\/fr\/products\/performance-radiator-for-jaguar-xjr-2006-2009-4-2l-automatic","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
