Description
The Mishimoto MMHOSE-MIA-90HHBK is a black silicone hose kit engineered specifically for the 1990-1991 Mazda Miata, built as a molded-assembly, OEM replacement fit for owners who want a factory-style hose that stands up to more than a stock rubber hose can handle. Every hose in this Mishimoto Fabrication kit is constructed from a dual layer of high-grade silicone reinforced with heat-resistant embedded fibers, giving it a Performance grade rating and a maximum temperature rating of 330°F.
This kit is a straightforward way to replace aging, cracked, or heat-fatigued factory hoses with a part designed for efficient heat reduction and increased pressure tolerance. The silicone hose construction is rated for a maximum working pressure of 40 PS and a burst pressure of 50 PS, so it’s built to hold up under demand while keeping the molded-assembly shape needed for a clean, OEM-style installation. As with other Mishimoto Fabrication products, it’s backed by the Mishimoto Lifetime Warranty, giving Miata owners confidence in a component that sees regular heat cycling and pressure under the hood.
