Spoon Sports Reinforced Radiator Hose - Civic Type R FK8 Superchargers machined with a smooth interiorDuring sports driving where the engine speeds up and down rapidly, the stock radiator hose will collapse like a straw due to suction pressure and vibration. This is especially true if you replace it with a larger radiator because it sucks up a lot of water. In sports driving, the problem is not rupture due to high water pressure, but the phenomenon of ``collapse'' due to suction pressure. Once "collapse" occurs, it will not recover even at idle speed
