The factory main fuse box cover cracks, fades, and disappears. Mazda discontinued the original (FD31-66-761). A cracked or missing cover is one of those details that announces neglect in an otherwise clean engine bay. This is a direct replacement.
Printed in black ASA — the correct material for anything that lives under the hood. Heat resistant, UV stable, and dimensionally accurate to the OEM fuse box it mounts on (FD31-66-761).
Available Versions
- Embossed — Fuse layout and amperages cleanly embossed into the surface.
- Blank — No markings. Clean finish for minimal or custom bays.
- White Text — Amperages printed in white material. High contrast, easy to read.
- Red Text — Amperages printed in white material. Low contrast, more subtle.
Installation
Direct friction-fit replacement. Align the cover over the main fuse box and press into position. No tools, no cutting, no drilling.
Fitment
Fits all FD3S RX-7 production years. Replaces Mazda part FD31-66-761.
Materials
Black ASA filament. Chosen for engine bay applications — excellent heat resistance and UV stability compared to the original ABS cover.
Designed, engineered, and manufactured in-house to exacting OEM standards.
