Hey i picked up my set of Taylor Spiro Pro 8mm wires on the weekend, look real nice (blue), nice strong construction and flexible. I measured the resistance of similar length wires from Napa and the Taylors. Huge difference, for the Taylors it was about 800ohms, for the Napa ones it was 12000ohms. Can't wait to put em in, i was busy building a new garden with my dad this weekend. They were on sale for $67CAD, AC Delco was selling wires for $64CAD not bad i guess.

how long are they supposed to last with daily driver type use (and the occasional RUSH )?

Well one reason i chose taylor was because of there good construction, they dont look cheap, Ive seen taylor wires used alot on old muscle cars, alot of 3.8L turbo buick guys use taylor and all gave em great comments. Lookin at them the terminals are different not the usually boot with the end bend back and crimped, its pressue closed with a plastic type material, whole wire is good up to 600F, the silicon exterior makes it very flexible. I have a feeling i wont have to replace these for a longg time. Though Magnecore seem good to, strong contruction.
