I have Autolite plugs & the pro series wires & I paid a more for them, about $70 ...no rebate either (*&%^%)!!
They have been FLAWLESS at this point, but I have only 10,000 miles or so on them. I was quite happy with the quality & fit. They are ever so slightly larger than the stockers, but I was able to stuff them into the plastic clip thingies without a hastle. They "snap" right onto the plugs, so you know when you get a good contact.
They are NOT numbered. You will have to check lengths & replace them one at a time to be sure of the routing.
I hope yours work well for you too.
