Description
The Mishimoto MMHOSE-RX-LSBL is a purpose-built silicone radiator hose kit engineered specifically for Mazda RX-7 FD chassis that have received an LS engine swap. Unlike a generic hose, this kit is designed around the unique routing and clearance demands created when an LS powerplant is dropped into the FD platform, giving swap builders a cooling solution tailored to their exact configuration.
As part of Mishimoto’s Cooling lineup, this silicone hose kit is intended to keep coolant flowing reliably between the LS engine and the RX-7 FD’s radiator once the swap is complete. Silicone hose construction is a common choice among enthusiasts and shops undertaking engine swaps because it is built to handle the demands of a custom cooling system layout, and this kit brings that construction to one of the more popular modern swap platforms. For builders searching for a Mishimoto cooling component made specifically for an LS-swapped FD RX-7, this hose kit fills that niche application directly rather than requiring hoses to be adapted from unrelated fitments.
Vehicle Applications
This Mishimoto silicone radiator hose kit is designed for the Mazda RX-7 FD chassis specifically when it has been fitted with an LS engine swap. It is not a hose kit for the factory rotary configuration but rather a dedicated solution for FD RX-7 owners who have already completed, or are planning, an LS swap and need cooling hoses matched to that setup.
