Performance Aluminum Radiator 2023 Plus Honda Civic Type R

The Performance Aluminum Radiator for 2023+ Honda Civic Type R improves cooling capacity, delivering a measurable reduction in operating temperatures (17% heat rejection, lowering temps on average 5–10°) for enhanced reliability under sustained load.

Designed by Mishimoto to maximize the radiator’s usable core volume, the assembly is engineered to utilize every millimeter possible for maximum efficiency and durability without sacrificing fitment in the Type R’s engine bay.

• All-aluminum construction — Provides a corrosion-resistant, high-conductivity thermal path for coolant, improving heat transfer and long-term durability compared to mixed-material designs.
• 17% heat rejection — Quantified improvement in thermal performance that translates to average coolant temperature reductions of 5–10°, lowering the risk of heat-related power loss and enabling more consistent operation under track or spirited driving conditions.
• Space-optimized core — The radiator is engineered to utilize every millimeter possible, increasing core volume and surface area within the vehicle’s available packaging for better overall cooling efficiency.
• Mishimoto engineering and validation — Built and tested by Mishimoto with a focus on performance and fitment for the 2023+ Civic Type R, ensuring component-level quality and repeatable thermal performance.

This radiator is intended for owners seeking a functional, performance-focused cooling upgrade that directly targets thermal management and component reliability during high-load operation.
