I bought these excellent wires and ran them 3 days and about 100 miles. I then realized they were not going to fit my custom exhaust heat shields which need straight/extended boots. 8mm w/woven fiberglass sleeves = 9mm OD. My cost was $184. Yours shipped in the CONUS for $140. OE packaging as you see here, includes dielectric grease - opened, but sparingly used.
