radiator for 911 BOXSTER/CAYMAN 3.6/2.7/3.4

Core Selling Points

    Tailored for Porsche 911, BOXSTER and CAYMAN models equipped with 3.6L, 2.7L and 3.4L horizontally opposed engines, DENAISHI® radiator is engineered to meet the extreme thermal demands of high-revving performance driving, with four premium advantages.

    1. Engine-Specific Precision Fit Strictly calibrated to Porsche’s OEM standards for horizontally opposed engines, it achieves seamless drop-in installation without modifications. The compact design perfectly adapts to the limited engine bay space of BOXSTER/CAYMAN, matching the cooling system interface of all three engine displacements, ensuring consistent compatibility with original components.

    2. Track-Grade Heat Dissipation Adopting multi-row aluminum alloy core and high-flow fin structure, it boosts heat dissipation efficiency by 40% vs. stock radiators. Specifically optimized for high-revving scenarios, it effectively reduces coolant temperature during full-throttle acceleration and prolonged track sessions, preventing power loss from thermal saturation.

    3. High-Performance Durability Built with full-aluminum construction and reinforced brazed joints, it resists thermal fatigue under extreme temperature cycles (-40℃~120℃). The anti-clog fin design maintains airflow stability, while vibration-resistant structure copes with aggressive driving on track surfaces, extending service life by 35%.

    4. Performance Preservation By maintaining optimal operating temperature, it protects engine components like head gaskets and water pumps from thermal stress. It supports mild performance tuning, making it a reliable upgrade for enthusiasts seeking to unlock the engine’s full potential without compromising durability.

Application Fields

Designed for Porsche’s sporty DNA, this radiator serves diverse high-performance scenarios:
