My belief is that it would be the one closest to the firewall on the driverside, but that is only a guess because that plug was so bad and I was getting a misfire on cylinder 8. I 'm wanting to try to change just that wire today to see if it helps. Thanks,

According to Wiki it's the passenger side, isn't it marked on the intake?

 

well i didn't know to look on the intake. didn't think about it actually.
I'll go out there and take a gander!

 

its the back cylinder on pass side. 2 4 6 8 down pass side, 1 3 5 7 down drivers side, from front to back

 

I feel dumb. I had forgotten they made things that simple. It was plain to see on intake. I would not doubt those are stock wires. They still had the plastic around them. I changed the wire and so far no check engine light. But it took a while after i changed the plug. SO we'll sit tight and see.
