i bought my car in january,it seems to be running good,it has 80k milles and is an 01,my question is should i go ahead and chang the plugs and wires,or wait,what is the recomended time to do this,i have seafomed the tank,and some time this week im gona do the rest of the seafome.

 

I would change the plugs for sure, especially since you don't know if they were ever changed before.

The wires could go either way. At 80k it might be a good idea, but it's not urgent unless you have some damaged/worn/burned looking wires.

 

I agree .
I suggest NGK TR55 (V power) about to $2.00 a plug and 8.5 MSD wires about
$60.00 with shipping for Texas Speed (great sponsor) and there is a great write up on the plugs on www.installuniversity.com

 

I run TR55 hear, but some off brand wires.

 

At 79K miles my plugs are still perfect. Gap is .057 and they look great.

 

suggests changing them @ 100,000 miles!!!

 

I'd change them now. I have a 99 Z28 with 87,000 miles now. i bought it with 81,000 miles and i thought it was runnin good until i realized the plugs that were in there were all bad. I changed the wires and the plugs this weekend with 8.5 msd wires, and the NGK iridiums, and it was runnin better then ever, i also got a cut-out this weekend so that might add to the beastlyness. Dont wait, change the plugs

 

change the plugs

 

I bought a package from the ws6store came with the NGK55s and MSD wires. Be shure to remove the pass coilpack makes changing the plugs a snap.

 

Regardless of what the dealers or manual may say. It is not a good idea to try to get 100k out of the plugs. Change them. And the wires too.

 

i run MSD 8.5 plug wires and iridium plug everything cost me about 160 buck 100 for the plug wires and 60 for the plugs, Devin

 

i know some sighns to a bad plug,but is there any sighns that i should look for in paticulare

 

Can't go wrong with the Stock AC Delco and aftermarket MSD's
