I have most all the bolt ons plus heads and cam, what spark plugs should I use. I just got her running tonight after being apart since I bought it in January. It was a little rough at first but she's starting to clear up now and run a little smoother. Right now I have autolite 104's in it but I wasn't sure if I should be using platinums or not? Anyone have any suggestions?

Yeeeeaaaa-yaaahhhhh

Definitely TR55's. Move to a TR6 if you ever plan on spraying it.

I just bought some of these for a total of $13. With how expensive everthing else is with these cars i expected to have to buy the ones that are $12 a plug.


I heard the stock wires would be good. Do u guys change thiese also?

TA TED

I think most folks use the stockers.

unit213

Stock wires are fine. No point in replacing them.

Should you use the TR55 Iridium plugs or just the regular TR55s?

TA TED

Regular copper here.

I put in some autolite platinum plugs that autozone said were the ones to use, but i think the car runs rougher and not as strong after i replaced them. I have only had the car dfor like a month, and my friend and I wen all through it, but it had original wires and plugs on it at 63000 miles. I am thinking about going with the ngk's instead since all i have read about them is good. Should i consider changing the wires as well? My mechanic friend said the wires look good still, but he has kida old school knowledge if you know what i mean, not that i dont trust him i just want a second opinon.

Are they good for a real long time or something? At what point is time to replace them. Has anyone else had real bad luck with the autolites? Yes I have searched. this was the best thread.

In my opinion stock wires are crap (Packards @500 ohms per foot), my $65 MSD 8.5 super conductor wires are 40 ohms per foot & allow for alot more current to pass. More current means better spark which means more fuel taken care of (More power made). JMO-Fred

And increased efficiency. Which transalates to better fuel mileage. (Only a percent or two, but hey, its something)

Get the irdium plugs if you can. Irdium conducts electricity better than copper. Plus, it'll live longer.

How many miles will these NG's last? Also, what about the GM Performance wires?

Thanks

allthatisman

I know this sounds stupid, but in one of my parts mags GM performance parts wires claim 600 ohms. Now is that worse than the 500? I am a "learning mechanic" so cut me some slack Ohms are electrical resistance, so the lower the ohms the easier the currnet moves through the wires to the plugs etc?

TA TED

Correct, resistance and current are inversely porportional. Resistance is simply opposition to current flow.
