Direct drop-in upgrade with hose fittings positioned for factory KA24 routing in the S13 chassis. A cost-effective alternative to premium aluminum radiator brands while delivering comparable cooling performance.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It Does\u003c\/h3\u003e\n\u003cp\u003eThe factory S13 KA24 radiator is a plastic-tank aluminum-core design that's been heat-cycling for over 30 years on most still-running cars. The tanks crack, the core gets blocked, and cooling performance falls off noticeably. This all-aluminum TIG welded replacement fixes those failure modes while providing better thermal capacity for KA24-T builds, KA24DE-DET conversions, and KA24s running aggressive timing or boost.\u003c\/p\u003e\n\n\u003cp\u003eComparable in size and cooling capacity to premium options like Koyo at a significantly lower price. Direct drop-in fit on the S13 chassis when running the factory KA24DE engine.\u003c\/p\u003e\n\n\u003ch3\u003eCritical Fitment Note\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eThis radiator is built for the S13 chassis with the KA24 engine.\u003c\/strong\u003e The hose fitting positions are sized for the factory KA24 layout.
