{"product_id":"csf-honda-civic-type-r-fl5-2023-high-performance-radiator","title":"CSF Honda Civic Type R (FL5) 2023+ High-Performance Radiator","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eCSF has a long and successful track record with Honda cooling systems, a history that includes manufacturing factory radiators for Honda Performance Development, and Honda used the CSF-built HPD Race Radiator on the FK8 Civic Type R TCR car before taking delivery of a new system CSF developed specifically for the FL5. This High-Performance version brings that same racing-derived engineering to the wider market, built for the FL5 Civic Type R and its DE5 Integra Type S twin.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe factory cooling system copes well with spirited driving and a daily commute, but starts to show real limitations once pushed hard on track or once tuning enters the picture, and the turbocharged K20C1 is no exception to running hot under load. Just like the HPD race unit, this radiator uses CSF's latest 5mm fin technology, with smaller fins significantly increasing heat exchange surface area for improved cooling efficiency, a design that increases heat transfer area by 20-25% over larger fin designs. A larger 2-row, 42mm aluminium core increases fluid capacity and the core's ability to dissipate heat, and CSF's exclusive B-Tube technology adds a further approximately 15% heat transfer improvement over regular oval welded tubes. Independent testing on an FL5 tuned to 294whp and fitted with a larger front-mount intercooler (which itself raises coolant temperatures by roughly 7% due to airflow restriction over the radiator) showed an 8°C reduction in engine coolant temperature with this radiator versus the OEM unit, a genuinely important upgrade for anyone running a larger intercooler or tracking their car.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eWorks with:\u003c\/strong\u003e Factory mounting location.
