RSPANTERA FD3S/FC3S Plug Cord

Car Maker: Mazda RX7
Car Model: FD3S/FC3S
Plug wires are a must-have for FCs, and also a part that needs to be replaced for FDs. Durability is important! Many plug wires work well right after installation, but wear out after a few months. We recommend NGK. They don't offer much in terms of power boost, but they do boost response and are extremely stable.

On the other hand, there are also plug wires that sacrifice durability in order to provide a stronger power boost. (※Please inquire about these.)
