Hey all,  I did a search on this and found nothing.  If I'm wrong please merge. 

Well it's come time to replace the plugs in our Enclave and I'm hoping someone else here has done it themselves...  I called a shop here locally and they want 270 bucks to do it.  Now I realize the plugs are all but hidden on the rear cylinders, but that seemed a bit high.  I'm guessing the plugs are about 10-15 bucks each or 60-90 bucks and the rest is all labor.

Anyone have any tips?  Even a tip like, DON'T DO IT!  lol

Mine is at just over 95,000...  I didn't see a post either...  If one of the other forums has it, please let me know.

I wonder if it's one of those "dropping the engine" things.

Please report back on specifics if you do the work yourself. IE, is it a 1, 2, 3, 4, or 5 wrencher.

I would hope not; although the back side might need to be accessed from the bottom i.e. have it on a lift

OK so I delved into it tonight to see how bad it would be, and found it to be pretty easy.  It's a little tight getting your arm over the intake and into the back head but it's pretty open once you get into it.  The front ones are a breeze... :Smiley I'll take pics of tools and the such as I go along as well.

I was quoted 270 bucks to do the work and I bought the plugs for $10.50 per plug.  I went with Autolite XP iridiums Part# XP5263  The stock Delco's are made in Japan and these are actually made in the USA.  HUGE plus IMO.

So I hope to get to this in the next day or so as my schedule permits.

excellent news.
Please do report back on the use of the autolites.

I say this because on the Trailblazer/Envoy forums--- people installed other plugs  and noticed a performance drop.
The 4200 Vortecs inline 6-- worked much better with AC Delco Platinums and Iridiums.
(I think Denso were also OK)... but many owners were soon switching back to ACDelcos when the non AC plugs caused lower performance.

If they were losing enough power to actually notice, then something was a miss...  I tend to go with stock plugs as much as possible after a HUGE ordeal I had with some of those Bosch 4 electrode plugs.  I put them in my F-150 which by the way is a HUGE job and not one to do yourself...  After doing it, I had a HUGE miss in one of the cylinders.  I immediately bought Motorcraft and haven't had an issue since.

This LITERALLY look identical to stock only made in the USA and by Autolite.  I'll keep ya'll informed on what I find and take pics if I can.

Cheers,
Chris

I usually like the NGK for my vehicles after trying several others.

Agreed 100% but they were a non-stock item.  I'll try these and if I have any noticeable issues I'll take them back for a refund and install stock.  It's my wifes car so it doesn't have to be fast! lol  That's what the G8 is for...  >Cheesy

I DO have to flash the trans with a tune though.  The thing is BAD!

I too had poor results with the Bosch plugs in my Astro Van ( pre-Enclave ), which were resolved by returning to the stock plugs.

As for flashing the trans, I wonder when we will be able to plug our vehicle to a USB port on our laptop ( or directly to the internet ) and download firmware updates just like we can for other electronic devices...

Well that's basically what I'm going to do with the tune I'm buying.  It would be nice if I could plug my cars into iTunes though...   blob

Please tell me that you are flashing the G8 and not the E.  I am going to be SO jealous.

lol. The G8 was flashed a long time ago.  The same company is going to do the "E" as well.  He claims 18-20bhp and much better trans behavior.

Ok got the plugs in!  More to come later, but let me say they were easy peasy lemon squeezey! 

Anyone who pays to have these done is either lazy or nuts!  lol

lol so am I in most situations but this took me 1 hour and it would take me less now that I've done them.

I was quoted 270 bucks to have it done and spent 60 on plugs.

I thought I remember you saying that VMS was going to do the tune, is that correct?  Did you have them do a 93 specific tune or just correct the AFR and timing to be a little less ECO friendly.
