Radiator Porsche 991 & 718 Right Side

The Radiator for Porsche 991 & 718 Right Side by CSF Cooling is engineered as a direct replacement core for modern Porsche 911 and Cayman/Boxster models that demand precision cooling under demanding driving conditions. Whether you're tracking your 991 Turbo or pushing your 718 GTS on weekend canyon runs, thermal management is non-negotiable—overheating costs you power, reliability, and engine longevity. This right-side radiator assembly restores OEM-equivalent cooling capacity after damage, deterioration, or upgrade scenarios where factory units fall short of performance demands.

CSF designs this radiator with high-efficiency core construction optimized for the 991 and 718 platform's unique engine bay layout and cooling circuit specifications. The unit is built to handle sustained coolant flow rates and pressure cycles that modern Porsche turbocharged powerplants generate, with durable aluminum construction and brazed tanks that resist corrosion and maintain structural integrity through thousands of heat-cycle transitions. Proper coolant circulation through the right-side radiator ensures even temperature distribution across both cooling cores, preventing hot spots that can trigger knock sensor intervention or detonation in high-boost scenarios.

Installation on 991 and 718 models requires basic mechanical competency—drain the cooling system, remove the impact panel or bumper trim per model year, unbolt the radiator supports, disconnect the upper and lower hoses, and slide the old unit out sideways. This radiator mounts directly into the right-side position without modification or auxiliary brackets, making it ideal for track-day enthusiasts, performance shops, and DIY mechanics rebuilding cooling systems after collision repair or proactive thermal upgrades. Dimensions of 19 x 8 x 22 inches ensure fitment clarity; always verify your specific model year and confirm any dealer-specific connector variations before ordering to guarantee seamless integration with your Porsche's existing plumbing.
