Over decades of heat cycling and high cooling system pressurization, these factory plastic tanks embrittle, leading to micro-fractures, seam separation, and sudden catastrophic coolant loss. Furthermore, the single-row factory core easily falls victim to internal scale buildup and external fin degradation, crippling thermal conductivity and causing rapid coolant temperature spikes under sustained boost or track conditions.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis dual-row performance radiator is engineered from 100% brazed aluminum to restore and elevate thermal capacity. Featuring precision TIG-welded end tanks and a robust 40 mm brazed crossflow core (500 x 368 mm), it maximizes heat transfer surface area while eliminating failure-prone elastomer gaskets and crimped plastic seams. With heavy-duty mounting rails, integrated sensor ports, a dedicated drain fitting, and standard 1.5-inch inlet\/outlet connections, it drops directly into the factory location without chassis modifications, delivering sustained heat dissipation against high-load heat soak.\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; margin-bottom: 20px;\"\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;\"\u003e1986-1991 Porsche 944\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;\"\u003eM44.51\/52, M44.41 \/ Type 951, Type 944\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;\"\u003e217-247 hp \/ 243-258 lb-ft (Turbo) | 208 hp \/ 207 lb-ft (S2)\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;\"\u003e95110603150 \/ 95110603103\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1986-1991 Porsche 944 Turbo 2.5L Manual Transmission\u003c\/li\u003e\n  \u003cli\u003e1989-1991 Porsche 944 S2 3.0L Manual Transmission\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the Type 951 944?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 1986-1991 Porsche 944 equipped with the M44.51\/52 and M44.41 engines paired with a manual transmission.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan this radiator be used with an automatic transmission?\u003c\/strong\u003e\u003cbr\u003e No, this unit is engineered exclusively for manual transmission layouts and does not integrate internal automatic transmission fluid cooling loops.\u003c\/p\u003e\n\n\u003ch3\u003eThe Porsche Precision Standard\u003c\/h3\u003e\n\u003cp\u003eTransaxle Porsches demand uncompromised thermal stability to protect high-strung inline-four engines from head gasket failures and cylinder distortion.
