The Koyo radiator for 2002–2006 Acura RSX Base and Type‑S manual-transmission models is a vehicle-specific replacement core; note that this installation requires a non‑OEM radiator cap. It matches mounting and hose locations for RSX manual cars and provides the correct dimensions and connections for owners replacing the stock radiator during repair or upgrade.
