What is the life expectancy of a set of plug wires??

[The Shape]

I have a set of motosport wires right now. Just wondering how long they should last on average?

hard to tell i would change them every 30-45k

depends how long before they touch the headers

30-45k sounds about right

Depends alot on how hot your coil is. I had an olds with DIS, you know the 3 coil packs? It ate a good set of wires once a year. When you see a light show under the hood at night, its time. You can measure resistance per foot and check specs to see if they are within tolerance, but I have not done that. I have found big differences, checking the difference in resistance from one brand to another. I chose wires of the same length and found the wires I took off my car to be quite a bit better than the ones I'm running.

I have the accel coil (the TFI replacement coil not the old coke can style) think it is strong enough to make a difference.

Maybe. Look for the light show at night. Mist them with a little water from a spray bottle to simulate high humidity. Check resistance per ft on them and the ones you are thinking about buying.

I take it you are not very pleased with your recent plug wire purchase. What brand did you buy so I will not get the same ?

They are Bosch, best quality they had at Discount. They work fine, had them for years now, but the old ones I have are better. They are Packard 8mm, never heard of them and they were on it when I got it 3 yrs ago. I replaced them along with alot of things trying to repair a part throttle pop in the intake. Turned out to be crappy GP Sorenson injectors.
