Description
The Mishimoto RX-7 FD Silicone Hose Kit, part number MMHOSE-RX-LSBK, was engineered specifically for Mazda RX-7 FD owners who have swapped an LS1 V8 motor into their chassis. Built from dual-layer, heat-resistant silicone with embedded fibers, this black performance hose kit is designed to bolt in with a direct OEM replacement fit rather than requiring custom fabrication for the LS-swapped cooling system.
Because the LS1 swap changes the demands placed on an RX-7’s cooling passages, Mishimoto developed this hose kit to handle the added heat and pressure that come with a V8 conversion. The dual-layer silicone construction combines high-grade silicone with heat-resistant embedded fibers to efficiently reduce heat and increase pressure tolerance compared to aging factory rubber hoses, while the black performance-grade finish is rated to a maximum temperature of 330°F. As a Mishimoto cooling product, it’s backed by the Mishimoto Lifetime Warranty, giving LS-swap builders a dependable hose solution for a demanding engine bay.
Vehicle Applications
This Mishimoto silicone hose kit is a vehicle-specific fit developed for the 1993-1995 Mazda RX-7, covering the RX-7 Base and RX-7 Touring trims across that full 1993-1995 range, as well as the RX-7 R1 for the 1993 model year and the RX-7 R2 for 1994-1995. It is designed for these RX-7 FD chassis cars that have received an LS1 V8 motor swap, providing a direct-fit cooling hose solution rather than a universal hose that would need to be trimmed or adapted.
