Description
The Mishimoto MMHOSE-IS300-01BK is a black silicone radiator hose kit engineered specifically as an OEM-fit replacement for the Lexus IS300, delivering the dual-layer construction Mishimoto is known for in a cooling-system upgrade sized just for this platform. Built with high grade silicone reinforced by heat-resistant embedded fibers, this kit is designed to handle the demands of both daily street driving and track use.
Cooling system reliability starts with hoses that can take the heat, and this Mishimoto silicone hose kit is rated to a maximum temperature of 330°F, offering increased pressure tolerance alongside efficient heat reduction compared to aging factory rubber hoses. Because it’s a direct-fit, OEM-replacement design, installation follows factory hose routing without modification, making it a straightforward upgrade for anyone looking to refresh or reinforce their IS300’s cooling system. Each kit ships with two silicone hoses and is backed by the Mishimoto Lifetime Warranty, and this particular listing is finished in black, with blue and red also offered for those who want to color-match their engine bay.
