Best plugs for 3100

[98montels]

Ok so I tried the search for about 20 minutes and didn't come up with the result I wanted so.....I'm wanting to replace my spark plugs in my 3100, its in a 98 monte LS.

 

Couple questions tho.

 

1. What brand should I go with (like best quality/ for the price)

2. Would it be best to get double platinum right? I know single platinum is the cheapest type and was told they fowl out sooner and what not.

 

And another thing I noticed is the acdelco double platinum's are pretty expensive compared to say bosch I believe it was.

 

LMK guys I know it's pretty straight forward but I'm just looking for a little input first.

Stock Delco's work best...at least I hear.

Stock AC Delco's. I have used NGK Iridium's in a 3.4 with good success, but you can't go wrong with the stock Delcos.

 

As for platinum, don't bother. There is a chance that it will actually perform worse with the plats.

What exactly is a double platinum?

 

I thought it was the electrode was platinum and the deal that the electrode arc's to (forgot what it's called) is platinum too.

 

On a side note about them possibly being worse, a buddy of myn changed his plugs in a jeep 4.0 inline 6. He used oem replacements and all it did was misfire, we even took them out and regaped them. Had to switch to the double platinum and that fixed it.

 

Thanks

just stick with the regular Delco's.

In '98 it probably came with regular platnum plugs. Just stick with either AC Delco or NGK.

[98montels]

Alright then. So OEM replacements it is then I suppose.

 

I guess the OEM replacement plugs are single platinum I think too.

Jeep =/= GM

 

 

Stock OEM A/C Delco all the way

I've had good feedback using Delcos, and recently I'm running NGK TR55's.

[cutty]

I use regular ac delco's.

 

But i have also seen NGK's that came in a gm box from the parts dept. of the dealer.
