View Full Version : Tune-up
I need some advice here for a tune up on a 93 stealth r/t. I plan on changing my plugs, wires (ngk), and the fuel filter. I did some research on this topic, one web site sugguested that the Intake Plenum Gasket as well as the Throttle Body Gasket should be changed, is this really necessary? Another question is, did the car come with cooper NGK spark plugs or the platium ones?

I just had a tune-up done on Friday, changed plugs, wires, and fuel injector seals. None of the gaskets were replaced as they were apparently in good condition. The car came from the factory with the NGK platinum plugs. I know some of the guys on this and the international board like using the copper plugs for a little extra poop. But I understand they don't last nearly as long as the platinum ones. Since I didn't want to go through the effort of taking the plenum off in 30K kms to replace the plugs, I went with the platinum. So I guess it depends if you want to save a few bucks, and don't mind ripping the top of the engine off more often. Me, I'm lazy! ;)

how much did the plats run you.
Pick up a set of coppers, 1 heat range colder than stock...they will run you maybe $15.
I don't mind taking the plenum off once a year. It only took DSM Power and I 8 hours the first time...lol.

...and I'll be there next time, watching and drinking the beer that you were saving til after you've finished the job! :D
Now how could I have forgotten about price. :rolleyes: That's the killer. One platinum plug costs almost as much as 6 copper ones. If you are going to pay someone else to change the plugs, I'd go platinum. If you do it yourself, and aren't charging yourself $75/hour, the coppers would definitely be the most cost effective.
Notice I didn't mention anything about performance? I haven't heard about any dyno numbers between the two types, so you have to take it for what it's worth.

Maybe we should have a plug removal party... might be easier if we all do ours at the same time. And ya.. I think a 28 pack might be required.
so should i go for cooper ones or the platium spark plugs...like will i really notice the difference between the two, besides in the pocket book?

Are you doing the work yourself? If yes, then consider the copper.
If you are paying a mechanic $75/hour, it'd be cheaper to go with the platinum, because you'll probably have to pay him to do it again next year/the year after, depending how much mileage you put on the car. I'm only guessing, but for a good mechanic, it'll probably be a 2 hr job ($150), so you're not saving any money.
Since it was my first time, & my car was basically stock, I took the conservative route, used the platinum, & I won't have to worry about it for probably another 5 years. I don't want to spend 8 hours every year or two to save $60. If your car has got some serious modifications, then you might notice the difference that the copper's make. On a stock motor, I don't know if there is much a performance benefit.
Now if someone could tell me that I'd get 20hp from the coppers, I'd definitely reconsider. But my mechanic recommended the coppers, so that's the way I went.
Now about those Red Wings?!

If you plan on raising the boost, go one heat range colder.
I went with one range colder copper NGK's and it solved all my 'spark blow-out' problems.
thanks for the advice.
Since my car isnt a twin turbo, i wont have to worry about boosting, and since i wont be adding much modication in terms of horsepower i will stick with platium plugs.
As for the Red Wings, it was a fluke, Cujo was a big disappointment :angry: but all i can say is they have won 3 cups in the past 6 years and thats more than anybody can say about their team :D
ps. leafs suck!!!

what are you talking about? It must be your eyes. Have you been drinking?
...just kidding.
I have no idea how it can take 2 guys 8 hrs to change plugs.....didnt you use wrenches?
My first time it took an hour and ahalf...
less each time after that...
You guys are going to scare everyone away!
One thing about plugs that I've wondered....if you are running high boost, although plats will last longer, will they maintain their gap through out the entire 5 years? i doubt it....but I could be wrong...either way, I still like to get in there every year and re-check things....coppers did feel slight stronger I have to admit...but you have to have the interest in going in there more often for sure if you use them.

"if you are running high boost, although plats will last longer, will they maintain their gap through out the entire 5 years? "
Well I've had my car for just over 12 years now and I have only started running higher boost over the past few years. New plugs were put in roughly 2.5 years ago and now (the front three at least) they have probably lost their gap. Lots of white residue, hesitation at high rpms etc...
I need to have this looked at when I have time...

Add improper tools, dropping things in the engine bay, a broken socket a very stubborn bolt, and there you go. 8 hours...
