Developed through extensive real-world and endurance testing, this vehicle-specific kit addresses oil temperature rise under high-load driving, a key weakness HKS identified in the FL5 platform. Inheriting the proven left-fender layout from the FK8 while redesigning cooling performance for FL5 characteristics, the S-Type core (200x122.5x48mm, 9 stages) is positioned for maximum efficiency without affecting water temperature or air conditioning. A large dedicated air duct and air guide actively direct fresh air to the core, while optimized discharge airflow ensures complete system efficiency. The result is approximately 15°C of oil temperature reduction, stabilizing oil temps around 125°C in 26°C ambient conditions where stock exceeds 140°C, plus a 3-5°C water temperature reduction for stable power output.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eS-Type oil cooler kit for 2023-2026 Honda Civic Type R FL5 (K20C)\u003c\/li\u003e\n\u003cli\u003eAddresses high-load oil temperature rise identified through HKS testing\u003c\/li\u003e\n\u003cli\u003eLeft-fender core placement (200x122.5x48mm, 9 stages) for efficient cooling\u003c\/li\u003e\n\u003cli\u003eDedicated large air duct and air guide for active fresh-air introduction\u003c\/li\u003e\n\u003cli\u003eOptimized discharge airflow for system-wide thermal efficiency\u003c\/li\u003e\n\u003cli\u003eApprox. 15°C oil temp reduction; stabilizes at ~125°C (vs. 140°C+ stock)\u003c\/li\u003e\n\u003cli\u003eReduces water temp by 3-5°C for stable power output\u003c\/li\u003e\n\u003cli\u003e#10 oil hoses, thermostat housing, and mounting hardware included\u003c\/li\u003e\n\u003cli\u003eUnpainted resin air duct included; optional dry-carbon duct available (15999-AH001)\u003c\/li\u003e\n\u003cli\u003eBumper and splash shield modification required (template included)\u003c\/li\u003e\n\u003cli\u003eReference installation time: 6 hours\u003c\/li\u003e\n\u003cli\u003eRequires 5.9L oil (approx. 500cc additional)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HKS","offers":[{"title":"Default Title","offer_id":47259644854374,"sku":"hks15004-AH105","price":1880.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0075\/8703\/7237\/files\/0b00e7c166f07154de1c1860418102adL.jpg?v=1790190058","url":"https:\/\/jdmuscleusa.com\/products\/hks-23-26-civic-type-r-fl5-s-type-oil-cooler-kit-black","provider":"JDMuscle","version":"1.0","type":"link"}
