So have been told by many of you to go with the ACDelco Plugs.  I can see there is Double Platinum(AC 41962) But where are the Iridium's for my truck??  I have checked all the parts stores(Napa/AutoZone/Orilly's, etc) and none show the Iridiums that fit my truck 2000 GMC Sierra 4x4 1500 4.8.  

 

When searching I see the ACDelco 41-110 but no where does it show that it will work for my truck.  Please help as I want the ACDelco's Iridiums for my truck.

I am sure I am right in saying that the 41-110 will work for my 2000 Sierra but want confirmation from you guys.  Why has the data not been updated at the parts stores showing this plug works for my truck??

I believe that is the correct part number for your truck. I don't know why they say it won't work. If you want an alternative you could go with these NGK 7397 {Click Info Button for Alternate/OEM Part Numbers} Iridium IX

I ran these in my 6.0, yes they fit the 5.3, for a few months before stepping down to a colder plug cause performance engine. Maybe 5k miles? but they worked perfectly.

Did not specifically ask them but when using the filter to fit my truck at all these sites none of them show working with my truck.  So just seems that the parts stores were never updated with showing the ACDelco Iridiums working.  I did read some reviews stating they work for the same years Silverado's and GMC Sierra's so thats why I know they are fine.  Will go with the ACDelco Iridiums 41-110.

This is a little off topic, but still relevant I think. What I can say for sure, is that there are counterfeit spark plug manufacturers. The plugs are cheap copies and they can fall apart inside your engine, cause major damage. I have bought plugs from eBay that turned out to be fakes. I returned them to the seller, rather than installing them. So what ever plugs you get, just make sure that your plugs are genuine before you install them.

I have actually been reading about that on Amazon and eBay so told myself I am ONLY going to purchase from local parts store.  This will ensure that I will not (hopefully) run into that issue.  That is one part that I want to be sure is 100% genuine.  Thanks for the info.

Is what AC Delco has to say.

I went to AC Delco's web site and keyed in your info.

I say Bosch makes good plugs for any vehicle, BUT in my Metric motorcycles I use NKG always.

The old wisdom AC Delco in GM, Autolite in Fords, and Champions in Mopars still holds true so far as I know. I have used Bosch with good results, as good or better than AC Delco. Just because it's European doesn't necessarily make it better, just different.

Really Bizzare that AC Delco does not show the 41-110's(Iridiums) when you search by 2000 GMC Sierra 1500 SLT 4.8.  

 

I ended up swapping out the Bosch Platnum's with the ACD's 41-110's(iridiums) and I tell you I noticed right away a difference.  Better idle and better throttle response right off the bat.  Reason I did was I just was not happy with the Bosch's, rough idle and not as good throttle response.  I am not saying Bosch is not a good brand/company they have been around a VERY long time I just feel some products go better with certain applications/vehicles than others. This is one of those situations.  

 

To back to what started all of this, had one spark plug go bad(they were NKG Iridiums that am sure have been in truck for 80-100k(not sure as I bought truck and have had just 10k miles).  The NKG's were pretty worn.  Just wanted to get back on road so bought Bosch Platinum's.   Just was not happy with them.  Did research and asked questions and you guys all told me to go to AC Delco.  So did and sure am glad that I did.  

 

So for all of you out there on the fence about going with one of the other brands just stick with OEM ACDelco.  Just do it.

Old school wisdom. The engineers at GM, Ford, or Chrysler are not dummies. If the factory recommends X stay with X.

I thought it very weird that AC Delco didn't list a iridium plug for that application, maybe COVID has kept the data base from being updated?

I figure it's because since iridium is good for around 100k on wear. For a plug change on a high mileage/20 year old vehicle they probably are thinking Platinum or Double Plats are a better way to go. Cheaper also. I'm sure many people won't opt for the higher $ plug. Plus don't forget prior to 2004, iirc, Iridium as not OE. That being said, most catalogs don't show iridium as an option for my 2004 even though they were OE. They push the Plats.

      I like the idea.  I would pick diesel if I had a choice. I need pictures though.

      Help purchasing a touch screen digitizer

      By newdude · Posted

      I've installed cheap eBay new aftermarket digitizers before.  They work.  Did a bunch of Cadillac CUE (aka Cadillac's MyLink) for someone years ago.  They all worked fine after the repair.    That number 22740886, that is a component part # for GM.  You can use it to search, but its not something that's obtainable at the dealer level.     So pretty much any of these will work - 2015 Colorado Digitizer for sale | eBay

      Exhaust heat while towing!

      By fondupot · Posted

      You can install tailpipes that direct the exhaust sideways vs the OEM one that goes straight back. There are several on the market, do you own research. HOWEVER, you need to make sure the Venturi vents are still intact, otherwise it will throw a engine code. There is a sensor somewhere that detects back pressure on the exhaust. And if it doesn't collect the correct metrics, it will throw the truck into limp mode.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      "Teardown" is complete. Head surfaces are clean and ready, new intake is prepped and ready. Coolant drained and water pump is removed, radiator is removed, new hoses and pump are ready.   The replacement intake is also from a '95 (with I think 260k, the odometer said). Noticeably less pitting where it covers the rear coolant passages. I'm not sure if that's a tribute to more frequent use, more frequent coolant changes/upkeep, or if the intake was machined at some point. But it appears I found a good one.   My coolant hoses were original, and the lower hose still retained the factory spring inside. It's not really rusty, but it's got deposits all over it. Unsure if I should re-install it (will thoroughly clean it first). Someone said hose technology has gotten better since 1995 (has it?) and I don't need the spring. I think modern EPDM is what made those hoses last from 1995-2026, so it's a question of how much suction can the water pump really pull, and will it collapse the hose without a spring?   I'm stopped and waiting for parts, however.   When I first brought the truck home, the fan was intermittently hitting the radiator shroud. I could see someone had monkeyed with the shroud (put a bunch of cardboard as a spacer between the upper/lower shroud halves. Someone said the motor mounts have likely failed and the engine has sagged. I wasn't sure I believed that. The engine is really solid in its mounts: To remove the old intake I *just* nearly permanently welded to the heads with freshly cured RTV and gasket snot two weeks ago, I literally had to use the arms on my lift and a chain with a bolt attached to the intake to pull it loose. It almost picked the front of the truck off the ground before ....scuuuuuuuuuuup.... I could actually hear the gaskets tearing and it broke loose and the whole truck settled back down. Motor barely moved.   SO, those parts I'm waiting on... The lower radiator mounts/bushings had completely failed. The radiator needs to be insulated from the rad support, and the bushings help the rad stand at the correct height. The plastic "baffle" was also destroyed at some point. Someone had attached the shroud to it incorrectly, overlapping a joint that should have been underlapped, creating another suspect issue potentially causing things to hit the fan. Broken tabs, side is busted off, and it's perma-formed/bent where it was jimmied incorrectly.   The baffle? Unobtainum. Long since discontinued from GM, of course. Aftermarket/capa/chinese? Also unobtanium. In GM's infinite wisdom, it appears there are at least two different variations whether the Blazer is 2 or 4 door, and I can't yet tell if they shared the same part with the S-pickups. Plan B, if I can't find a viable used one, will be to create a bracket to re-assemble the critical joint I need to seal a gap with the shroud. But that will bug me, it won't be...perfect.   The water pump bolts appear to have been installed with...plumber's putty. I guess, sure, if it works...? I've found a few "backyard fixes" like that. Someone's been here before....   If I can't find someone to jam bamboo under my fingernails to fill my free time this week I think I'll install the driver's power window motor and replace the rear door speaker that's inop. I've got a genuine GM "9.5" ohm working replacement. Why GM used a non-standard resistance....nevermind. Of course they did, you can get more sound from a cheap factory amp that way.   And the saga goes on...
