Repeated thermal cycling causes standard factory rubber to harden, become brittle, and eventually crack. During aggressive driving, track days, or in forced-induction builds, these limitations become a serious mechanical liability. Expanding beyond their structural limits increases the risk of a blown hose, sudden pressure loss, and catastrophic engine overheating that threatens the integrity of the aluminum block.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eThis upgraded coolant hose kit uses premium-grade silicone reinforced with 3-ply nylon, achieving a full 4.5mm wall thickness. Unlike standard rubber, silicone maintains flexibility and structural integrity across extreme thermal variations, specifically engineered for operating environments ranging from -65°F up to 500°F. The heavy-duty 3-ply nylon reinforcement drastically increases burst resistance, supporting an 85 PSI continuous working pressure and a 245 PSI peak burst pressure. This prevents wall ballooning under high stress and ensures consistent coolant flow dynamics. The kit includes properly sized clamps for a direct, drop-in installation, permanently resolving OEM hose vulnerabilities.\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;\"\u003e2009 - 2012 Nissan 370Z, Infiniti G37\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;\"\u003eVQ37VHR \/ Z34, V36\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;\"\u003e328-332 hp \/ 269-270 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;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n \n  \u003ch3\u003eCompatibility\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e2009 - 2012 Nissan 370Z Z34 (3.7L VQ37VHR)\u003c\/li\u003e\n    \u003cli\u003e2009 - 2012 Infiniti G37 V36 (3.7L VQ37VHR)\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eThe VQ37VHR Reliability Standard\u003c\/h3\u003e\n  \u003cp\u003eUpgrading to reinforced silicone is an essential preventative measure for high-revving JDM platforms, ensuring stable engine temperatures and reliable cooling performance during spirited driving or boosted builds without the risk of unexpected pressure drops.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":48244931887352,"sku":"DS-ESH2LMEWX","price":74.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/radiator-coolant-silicone-hose-kit-for-nissan-370z-z34-infiniti-g37-2009-2012-3-7l-1.webp?v=1776298283","url":"https:\/\/performancechiptuning.com\/products\/radiator-coolant-silicone-hose-kit-for-nissan-370z-z34-infiniti-g37-2009-2012-3-7l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
