so I was going to change the plugs in my 2003 gmc 2500HD 6.0 pulled the plug out to get number and it has 2 numbers on it:ACDelco 12567759 and NGK pztr5a 15. I have never seen this before but whatever, so I go to the parts store and they couldnt cross reference it over and their computer says its 2 different plugs. Another parts store couldnt pull up either number and a napa couldnt cross it either. So when I got home I called the dealer and he gave me: ACDelco 41805. Under the hood lists the plugs to be gapped at .060 but the dealer told me to gap at .040. I dont quite understand this, has anyone else had this experience? and they are 10 dollars a whack, I changed all 6 in my blazer for 20.

I haven't seen CAP on the forums all day.... check the WWI arena. :aok

First and foremost I only use NGK plugs in everything I own so that is the path I am going to take you down. The pztr5a looks like it was replaced by a PTR5D-10 ngk stock number 3784. These are the premium Lazer Platinum plugs. If you like spending $80 to change a set of plugs be my guest. I would just slap in some standard NGK TR5 2238. Gap both at .040 The TR5's will last plenty long and cost a lot less. I ran the V power plugs in everything from my turbocharged ricer to my Corvette Z06 and never had any problems.

I think I would call around to other parts stores before using something possibly different than factory.
My old pappy always told me to use only factory recomended parts.
-
I agree with using only factory plugs, the only place I can get plugs that match is at the dealership, never heard of such a thing lol. and the fact that both NGK and AC were on the plug :huh :huh oh well guess I get to spend 80 on a third of a tune up
-
It seems that NGK made those plugs for GM and the AC # is a parts number.
A quick check of a couple forums was all it took to find this out. whether or not you spend the money is up to you but I'm sure you can find a cheaper alternate.
:salute
-
if you only use factory why even make the post? Go get raped at the dealer. If the ngk v-powers ran fine in my Z06 and CTS-V I am sure they will be fine in your truck (btw I run them in my yukon xl also). :aok

I made a good portion of my money diagnosing cars that had a funny miss at idle.
I fixed them by putting OEM spark plugs in.
The service interval is 100,000 miles or more so that's where your savings occurs.
The reason for gapping 040 instead of 060 was instituted to ensure the vehicles made the epa mileage mandate concerning tune-up.
-
Look up the AC Delco website, they have an online catalog, you find your vehicle and then look up the parts for it.
You want an AC Delco 41-805, or if you want to use the AC Delco RpaidFire, you want a 6.
The 41-805 is $5.99 at Autozone, you'll probably have to order them for home delivery online. They have a $1.50 per plug rebate.
They have the RapidFire 6 at most stores for $4.99, no rebate.
The 41-805 is a double platinum, the 6 is not. My Firebird actually ran better with the RapidFire plugs than it did with the double platinum plugs, and they last about as long.
I prefer AC Delco plugs, or Champions, I will not use all the Bosch gimmick plugs, and rarely use NGK. I was a flat rate line tech in one of the best shops in the southeast for years. We used the factory plugs in 99% of the vehicles we worked on. We solved more problems taking the trick gimmick plugs out and throwing them away than you can count.

i have saved a good deal of money on gas by replacing the oem plugs with bosch or ngk. i have yet to see an "economy" car get 100,000 mile plugs from the factory, gotta be luxury/performance cars with that service interval.
-
The epa demands that service interval from all cars.

Real trucks don't have spark plugs.

i'mn a parts manager at a ford dealership the only plug we sell are motorcraft plugs-we get customers in all the time--telling us they changed their plugs 4,6,7 months ago and 80% of the time it's the aftermarket plugs they put in..so if your ride is a gm- u should stick with ac-delco--dodge--champion--ford/l/m motorcraft--etc..if thedealer is telling you use a different gap setting-maybe vehicle info has been upgraded...but if you still have your owners manual check under specifications it will tell you.if not i would use the gap setting under the hood..can't go wrong there...but people should only use the parts made by their vehicle manufacture--been a parts man for 27yrs

This.

I have 16 plugs in my car. I'l use OEM only.
-
Should be able to get a set of factory ACs at most autoparts stores for around 5-6 bucks each. With my mark up I sell them for 10 bucks each, and should only be an hour to install.

The thing about the platinum plugs is you change them the first time just after 100,000 miles and the next time after 200,000.

And they're almost always 30K miles past worn out when you do. They're fun to get out of the head, too. It's a really stupid idea, no matter what anyone tells you, ignition system components do not have anything near peak efficiency and quality past 50K miles.
If you're one of those unlucky souls, it'll cost you about as much to get a seized plug out of a cylinder head at 100K miles as it would have cost to have the vehicle tuned up 3-4 times.

I have to completely agree with this. Platinum plugs are most definitely a gimmick.
-
If your familiar with your parts supplier they'll ask you if the vehicle is missing when you go to get plugs if you have less than 100k. lol
I have seen where the price of the plugs has dropped dramatically.

This ^^^
Aluminum heads and steel plugs dont mix well and once seized they tend to remove the threads with the plug.Oh it's a simple enough fix but like capt.Virgil says the cost is likely way more than changing out the plugs 3 or 4 times.
Funny how the plugs last the same length as warranty... :rolleyes: Thats so the manufactures dont have to spring for the head removal and helicoil and associated machining.
I had the plugs done on my honda at 40k,werent due for another 60k but the service manager and I are friends so I said just do it. Later he said to me,good thing we changed them,1 was almost seized and had I have waited I would have been facing a nice bill to repair it. The service manager told the tech to be sure to use plenty of antiseize but even that wont help much after 4 or 5 years! Oh and I plan to replace them again at about 80k!!! :D

Hard to believe the griping over $6 plugs. One plug on a plane is $25 for a dirt simple massive electrode.
http://www.skygeek.com/urhm38e.html (http://www.skygeek.com/urhm38e.html)
Finewires - try $90 per plug times 12.
I pulled a Champion Finewire from a TN IO-550 the other day in Williamsport PA with a cracked insulator when it dropped out on 1 mag. The guy didn't have a spare, luckily I did and had my tools.
For you CFI wannabes out there, learn yr engines and how to diagnose and fix problems when it's a Sunday away from home.

You're not condoning being prepared again are you? :D

bought plugs total 76.56 only plugs any partstore could get were ngk's and had to be ordered, well I believe in AC in GM. on another note to you guys who fly. What happens if your are 2000 miles from home and you plane craps out? obviously a mechanic has to fix it, car mechanics dont always get to you right off, I am assuming aircraft mechanics cant get to everyone right off either or am I wrong? just something I thought of the other day.

was pretty busy at the shop today.
you should be easily able to purchase those plugs at any napa store.

call them again. the napa store. give them the application, not the part number. i know they have them. they'll have OE equipment, probably in delco, ngk, or autolight.
napa's website lists the gap at .040

i had 2 bad experiences with bosch plugs in the old 80's ford 5 liters. one time in a gm 5 liter. i go out of my way to not install bosch in anything i work on.

they have to rate them. i've seen it once or twice.

full set of plugs for my car costs 15 bucks. takes 10 minutes to do the job. may as well change them regularly.
bastards want $100 for a set of wires though. I'd almost prefer to do the rear plugs on my alero and get wires for less than half that.

My 98 Z-71 Truck had the 100,000 mile plugs and I ran them till 106,000 before I developed a miss.
I had gone in to buy plugs when it was around 50k and they asked if it was missing. I said no. They told me about the plugs and so I did not replace them at that time.

i think it was cvh? that said it? once you pass about 40-50k miles, those plugs ain't worknig as they should be. whether or not you feel it, they're not.
-
Seems odd to me to wait that long. In any case when changed, none broke off or were messed up.
-
By the time you get to 100K miles, those well worn plugs have put an excessive load on a set of plug wires, and the rest of the ignition system, increasing the chance of failures, and shortening their useful life. A good set of plug wires is between $50 and $120. One coil pack that feeds either 1 or 2 cylinders is at least $50. A cap and rotor for a system that uses the "distributor" to do nothing more than switch secondary voltage from one cylinder to another when the coil fires is at least $50. After about 50K miles, the loss in fuel efficiency from relatively worn plugs is between 1% and 2%, with gasoline over $3.00 a gallon in most places, and the efficiency loss only gets worse.
Tell me again how expensive a $6 spark plug is.
There are two reasons to claim 100K mile tune up intervals. One is to satisfy the EPA. The other is to sell vehicles to people too stupid, too cheap, and too lazy to have them serviced at decent intervals.
-
see, that's the problem.
everyone has a "friend" that always seems to know more than the guy that works on cars for a living. they seem to want to believe this "friend" who heard this or that on the internet, or they want to believe those little aol news snipits, or the news show that goes undercover, searching for crooked mechanics.
they don't think that we know what we're talking about, and since they don't "feel" anything wrong with their car, then we must be wrong.
i just went through a LOT on a lexus with an o2 heater code. this guy kept telling me his cousin, or friend, or nephew, or someone told him it was XXX. they were ALL wrong. it turned out he had a bad computer. but i had a helluva time convincing him of that. :rolleyes:

Question : If I run a to hot of plug in my F150 will it not burn up a piston ? I'm running 10 over in it now .
