Over time, constant cyclic heat loads and road chassis vibration cause micro-cracking at the tube-to-header plate joints and core-to-tank seams. A leaking or internally fouled cooler compromises the entire induction cycle, causing severe boost pressure drops, elevated exhaust gas temperatures (EGTs), excessive soot generation (black smoke), and unburned fuel waste across severe duty cycles.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eBuilt with an all-aluminum bar-and-plate\/tube-and-fin core structure, this replacement intercooler delivers optimal heat dissipation and withstands severe sustained boost pressures without splitting. Sized precisely to factory dimensions—featuring a 39-3\/4 inch core height, 11-5\/8 inch core width, and a robust 4-inch core thickness—it drops directly into the OEM front frame mounting points. With standard 4-inch inlet and outlet connections positioned identically to original factory routing, it restores turbocharger compressor efficiency, stabilizes air-fuel ratios, and eliminates thermal derating under maximum torque demands.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 Charge Air Cooler\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2008-2009 International ProStar\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e\n\u003cstrong\u003eMaxxForce 13 \/ Cummins ISX\u003c\/strong\u003e \/ \u003cstrong\u003eNavistar ProStar\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e450 hp \/ 1,650 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e\n\u003cstrong\u003e2591600C91\u003c\/strong\u003e, \u003cstrong\u003e2591552C91\u003c\/strong\u003e, \u003cstrong\u003e2591552C92\u003c\/strong\u003e, \u003cstrong\u003e2591552C93\u003c\/strong\u003e, \u003cstrong\u003e2591553C91\u003c\/strong\u003e, \u003cstrong\u003e2591554C91\u003c\/strong\u003e, \u003cstrong\u003e2591555C91\u003c\/strong\u003e, \u003cstrong\u003e2591559C91\u003c\/strong\u003e, \u003cstrong\u003e2601433C91\u003c\/strong\u003e, \u003cstrong\u003e2601435C91\u003c\/strong\u003e, \u003cstrong\u003e2608783C91\u003c\/strong\u003e, \u003cstrong\u003e3609885F91\u003c\/strong\u003e, \u003cstrong\u003e3609885F92\u003c\/strong\u003e, \u003cstrong\u003e3609885F93\u003c\/strong\u003e, \u003cstrong\u003e1E5936\u003c\/strong\u003e, \u003cstrong\u003e1E6406\u003c\/strong\u003e, \u003cstrong\u003e1S180131\u003c\/strong\u003e, \u003cstrong\u003e1S180132\u003c\/strong\u003e, \u003cstrong\u003e1S59360\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2008-2009 International ProStar\u003c\/li\u003e\n  \u003cli\u003e2009 International 5500i (with matching OE numbers)\u003c\/li\u003e\n  \u003cli\u003e2009 International 5600i (with matching OE numbers)\u003c\/li\u003e\n  \u003cli\u003e2009 International 5900i (with matching OE numbers)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the Navistar ProStar?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2008-2009 International ProStar equipped with the \u003cstrong\u003eMaxxForce 13\u003c\/strong\u003e or \u003cstrong\u003eCummins ISX\u003c\/strong\u003e platform, provided the original cooler matches one of the specified cross-reference part numbers.
