Fleece Performance coolant bypass kits meet the demands for more cooling that comes with increased horsepower. Your engine cooling system was designed to handle a 300-350hp engine. When you increase the power, you increase the demand on your cooling system and the possibility of problems that may lead to failure. Fleece coolant bypass kits feature a secondary thermostat that operates on temperature--not excessive pressure--solving excessive pressure problems before they become an issue by ensuring consistent temperatures across all six cylinders. Each kit includes high-quality AN O-ring fittings and AN hose connections with braided hose to ensure a leak-free installation. When there's a need for better performance, you can rely on coolant bypass kits from Fleece to supply the necessary components for assured greater performance.
