Spark plug wires used for an Impreza (GC8). SplitFire TC-FO3 spark plug wires, for STIVer.3. Although there were no particular problems, I replaced them with a different product because I heard it's better to replace them regularly, so I'm putting them up for sale. The resistance is 0.8Ω, and the ignition power is said to be 15 times greater. I've been using them for about 20 years, and there have been no problems, nor have they hardened, so I think there's no problem with use. Compatible with GC8 Ver.3 only (photo 4).
