Is this an original spark plug wire for 1991? Thanks in advance

 

Looks like it. I have some at home I took off of a low mile 89 and 92. I think they are the same.

 

Thanks TTOP, I assumed so, PACKARD and being numbered. My car is not low miles so I wondered.

 

My 85 WS6 has the numbered Packard wires. 56k miles

 

Packard is, or was the electrical division of GM. I haven't looked too closely lately but Packard Del-core seems to ring a bell. I'd imagine any combination of GM, AC, Delco, Packard, etc could be considered correct.

 

(should have grabbed those)

 

I changed mine out in 92 cause they were not cool looking enough. Big mistake! But the do look familiar. Black and boring. The 90 degree turns look familiar as does the white lettering. I may end up finding them laying in a box somewhere. Eps ill let you know if found.

 

Related question:
When I changed the wires on my 87 GTA, it had aftermarket plug wires but the coil wire said 8mm Packard.
From this I assumed all the original wires 8 mm.
The picture the OP has says 7mm.
Were original Packards 7mm or 8mm?
Or is it just the coil wire that is 8mm?

 

I was thinking 7mm sounds right. I wanted thicker wires cause they seemed cooler

 

I think they were all the same size. They may have used the #8 plug wire to make the coil wire.
