Tune-Up Time

[iJAC]

My 97' Eldo has been chillin in a garage for about a year and a half now. I think its time for a tune up amongst other things. Im trying to get some suggestions on brands for plugs, wires, air/fuel/oil filters as well as anything else I am missing... I also need pads and rotors I realize I could probably go with replacing everything with Delco's, but I was looking for something with a little more performance. Do the Platinum or Iridium plugs make a difference (worth the $9 per plug)?

I'd just stick with the platinum's unless you are just going for longevity.
A friend of mine has iridium plugs in his Northstar and loves them, but to me weren't worth the price.

OP,
Just go with the Delco plugs specifed in the manual. Don't improvise. As far as the other parts go, just buy quality. Delco's day as a premier parts source has passed, I assume for reasons of cost containment. The Delco wires I got were not, visually at least, of the same quality as the Delcos they replaced.

iJAC, There is so much written on tuneups here and in Northstar Performance that you're better off using the search button in the blue bar to find threads on tuneups, spark plugs, wires, coils, air filters, etc. Spend a couple of hours just searching around and believe me, it's all in here. Many times over.

Your car takes #41-950 ACDelco Platinum Professional plugs, gap is set at .050", torque to 13 ft/lb, no anti-seize. Use the proper ACDelco wire set. Remove the coils from the ICM and clean every contact. Follow the wiring diagrams. (They're also in here a hundred times......). Change the oil and filter, good brand of 10W-30 and proper WIX filter. Same for the air filter.

For plugs and wire look at www.rockauto.com.

Hey Sub,
Thanks for the overly confident cocky response . Simple questions require simple answers, I was just trying to get some info. I did use the search tool (I think that's what its called???) on the blue like colored bar towards the top. I kept getting information on tuning N*. I already use WIX filters purchased from Rock Auto, just wanted to see if there was anything better. I was also aware to replace plugs with Delco's, but once again as I stated I was looking for something with more performance (if applicable). By the way, thanks for the pics from ALL DATA!

Simple people require simple answers. Perhaps I pegged you wrong.

If iJAC had paid attention to the search he claims he did, he would have found that the OEM stuff provides the best performance. People ask for advice and then when you tell them something they don't want to hear they act like it's all your fault that they're on a fool's errand.

The OP worked himself into a snit because he's finding out there isn't much Pixie Dust for these cars..........

That's what he gets for getting his information from the guys down at Cooter's garage.

I changed my spark plugs (while back) with expensive Bosch Platinum IV (looking for extra umph). No later than 3000k later I got misfires, obviously I was looking for everything else but the spark plugs (witch were new, expensive and on expect good quality). 20k later in desperation I changed the spark plugs again with much cheaper AC Delco at Ranger’s and few other members advice (since day one). Well 40k later no misfire what so ever. I did change the spark plug wire set too (also AC Delco) and I must second NickySantoro, they don’t look the same quality (including no more cylinder numbering), but so far so good can’t complain.
Anyway conclusion … tires, oil, light bulbs, go with what ever you feel like, for the rest stick with OEM.

I just put in new AC's and it was worth every penny.
