AC Delco plugs

[BuckyBoy02]

Does anyone if there is any difference between AC Delco spark plugs bought from the dealer and ones from a parts/discount store?

Shite I thought it was more like 80-150% if not 200%. Of course this is dependent on what you're actually getting.

i was just guessing. . .i haven't stepped into a dealership, other than to look at a car, in over 10 years. . .

[BuckyBoy02]

That's what I was thinking too, just checkin. Thanks guys.

Buy Autolites instead...they are cheaper and they are the same plug made by the same company as the ACDelco plugs

[bad03xtreme]

Just get some AC delco at your local part store...

if you love your truck you will get e3's

care to explain? I can't think of one single instance where purchasing e3"s is better then delco/ autolites.

[montec]

I switched from Delco's to NGK's Will never use bosch again.

I hear people say that about Bosch a lot.

[BuckyBoy02]

Don't know what e3's are. But I did get the regular AC Delco plug (R43TS6), put em in ,and it fired right up. I posted earlier on the 4-banging part of this website about the non start typical issues for the Duke I had. It was the plugs! Spank me for NOT doing a tuneup earlier. Oh well. Will do the rest of the tuneup this weekend. The last plugs were AC Delco Rapidfire 1's. They worked great, but I decided to get the basic standard plug.

Had a set of Bosh platinum in an old 3.8l and That low compression engine pushed two of the porcelain out of the metal after just a couple of days.

horse power tv did dyno tests on spark plugs, the e3's gave better fuel economy and picked up a few pony's

[BuckyBoy02]

Joker Relentless: What is the name of the company that makes both AC Delco and Autolite plugs? Didn't know they were made by the same company.

I liked the powerblock before it became a giant infomercial for parts. They've lost 3 great hosts in the last year or so. The e3's do look interesting but I have not read or seen much on them yet.

But they cost like $25 each,
Id get Iridums first for $12 each

But still then....


Im gonna try some Denso's

Autolites lasted longer then the ACs but still not long enough.

sparkplugs.com

great site to cross reff n see plug specs.

Denso's look really good. Was gonna try them till I talked to one of there reps. Seems they only care if its going into some race car. I was doing a tune up on wife's GA @ the time.

[350X]

Well Im not ready to spend more then $3 per plug and the Denso's are about it in a regular type plug. over splitfire n all them other fancy ones above $3.


Ones like E3 one would have to d some searious miles to pay for them.

Even with better mileage it gonna takes allot of them to pay off a $200 spark plug bill.

I can get 11-12 sets of $1.98 plugs for that price. Or 1 set of plugs and 60 some gal of gas if the price was $3 a gal. Which I rather have.


8 Denso's $17 even on special order form them as I got 1 heat range hotter.
[was the only standard $2-3 plug I could get one hotter in too, which is also why I picked Denso]

[kjm762]

There should be no difference between the ACDelco plugs. As long as they were never dropped on the ground & broken, they should be the same. I have bitched at GM Parts reps for years about this same stuff.

[phantom_mia]

e3's are like $6 a plug, splitfire's when they came out were $5, word has it factory plugs are changing to e3's and that the old ac delco's were made by ngk

[circa]

I put in bosch Iridium fusions about 5k miles ago.
Seems to help a little bit over the autolites i think that were in there.
Dont know how long they will last but they helped.

If they last... they are worth the price.
If they dotn last... I wont be buying them again.

[montec]

I put NGK's in my '83 as they were cheaper and they were on hand vs Delco @ the time. I also got NGK platnums for the GA as the delco's didnt make it 60k before they were worn fairly well. I did however like the rapidfires back in the day, but seems CSK(now Ocrappy) didnt have them instock or couldnt get them for some unknown reason. I'll stick with NGK's as they are good for what I've been using them for and seems like the sportbiks, HD and dirtbikes are recomended to use them. Plus the price is right.

[rmoore911]

here's what i don't understand about people. . .i see people waste all kinds of money on cleaning products, on different brands of motor oil, and only stopping at certain gas stations because they carry such and such fuel when it was probably refined at the same facility as the bargin place down the street. . .but for some reason, those same people won't justify paying a couple bucks more for a quality spark plug, or they think shelling out $40 or more for plugs is outrageous. . .what other item in your car or truck can you purchase at around $5 a piece that can last 100,000 miles, that is as important as a spark plug. . .i'm not saying anyone is doing it really in this thread, but there are several threads on plugs in the various sections on here, and most of them have people bitching that a certain plug isn't worth that or that plug is overpriced. . .

[350X]

Maybe Im thinking of a diff plug, isn't E3 them pulse plugs, those are the last one HP TV did and they were ubar pricy not $6.



Only plugs that ever last a long time for me where the accell Ugrove plugs.


As of now AC n Autolites last about a year, or shuld I say a good year of service till I notice its time again.

Only the 90+ cars seem to have the ign system that will make plugs last years n many many miles.

[montec]

rmoore911,

Its like the whole chevy vs ****, or as some even do chevy vs GMC or buick vs Pontiac. Its all about there perception. I will run NGK plugs as I can as they have some good products out there, I do fill up @ only some certain gas stations(filling up and driving hrs and have the fuel freeze as it leave the carb is not fun), I will run Royal purple oil as they have a great product. I run either hastings(baldwin), Delco oil filters maybe a premium wix. I was running K&N air filters but they gummed up the TB so they are going out the door(and yes I know how to oil them properly) thinking of switching to AEM dryflow and giving them a shot before going back to paper. I am partial to brakes too, but to each there own. I have had good luck and back luck with many different parts companies so I have preferred choices that I use first, and if not available will go with the next best I know.

First, let me reword my post from earlier about this...I should have said that I've HEARD that they were manufactured at the same place and just slapped with a different logo. I'm not sure if that's true or not, its just what I've been told by different mechanics and autoparts salesman from several different areas of the country. I know that the name Autolite is owned by Honeywell and ACDelco is a subsidiary of GM, but that doesn't mean they are the one that manufactures them.

[350X]

Soon as my Deno's arrive I can compare the AC n Autolites, still got the AC I removed when Autolites were put in.

[BuckyBoy02]

Joker Relentless: Gotcha.

When AC Delco stopped making spark plugs, NGK and Autolite picked up their models, with Autolite making the majority of them.

Theres probably a good chance that some dealers have old AC Delco made spark plugs, which I would shy away from. Your basic double platinum Autolite plug will last forever.

I hope you own a good fire suite.

[01cherryreds10]

I've seen Delco plugs last over 130k and at that point they just started noticing engine performance issues. Not bad at all considering they are $3. And the Delco plugs are like $4 at a dealership last time I checked. That's employee pricing I have no clue about anyone else's price. I really don't understand why people put synthetic oil in a daily driver, considering the vehicle was built with tolerances in machining for regular oil. Same thing with oil filters. If it was a Corvette, sure I'd go to synthetic because that's what GM calls for. But even on Z06's GM still calls for the same exact filter you will find on many other vehicles like the Traverse and C/K body style with the 4.8/5.3/6.0.

AC and Autolite plugs are made in the same factory. it is split right down the middle, once side making AC Delco, the other Autolite.

the Ac Delco Irridium are made by NGK ( customer brought plug in, said AC Delco on one side, and the NGK logo on the other side)

AC Delco is just a box now.

while on the subject

AC delco, autocraft, motorcraft, everstart, and whatever chrysler uses are all made by the same battery manufacturer, just to the specs provided my the buyer. (hence the delco batterys going to shit recently)

Agreed to a certain extent. There are certain vehicles that use AC Delco batteries that have battery run down problems, and it's either the battery that is causing issues, or the vehicle's electrical system itself. It's hard to test especially since you need a battery to perform a voltage drop test

Long as the gap doesn't get to wide or they get fouled with oil or gas they shuold last forever.

I could of pulled my AC and my current Autolite, cleans n regapped them but I don't do that.

First hint of them not being up to par, out they go.

[01cherryreds10]

The center electrode wears away after time. If you look closely at a plug that's been worn down and compare to a new one you will notice wear in the sides of the center electrode, especially vehicles with coil packs that share a coil between two cylinders because of the wasted spark system that was designed.

you have alot to learn,young one. synthetic oil is sooooo much better than dino oil,plus oil filters are what keep you oil clean...do you really want dirt in your oil while its lubricating your bearings?

ok back to spark plugs

[rmoore911]

i was with him up until he brought up the oil statement. . .my factory plugs lasted 100k miles and they still looked to be in great shape. . .the reason i changed mine was because something just felt like it was missing out, and i had already removed the wires and plugs. . .no since of not replacing them at that point. . .ever since, the missing out feeling went away. . .though having the battery unhooked while i did the tune up screwed up the settings on my remote starter, and that was fun trying to get fixed. . .

Actually Delco just changed manufactures recently to johnson controls as did batteries plus which is why there batteries are rayovacs. Also interstates are shite too as they were the same as delco before. And I get a better deal on Delco's.

who told you that?

im sitting in the office of the factory that makes autolite, ac delco and motorcraft plugs right now . . . . were not split right down the middle. we run 3-5 million plugs a week and there labeled according to who ordered what.

[circa]

How about you guys test every plug made.
By running octane booster.

Which ever plug lasts the longest obviously is the best.

Sounds like you've totally worked in the Honeywell production plant in Fostoria OH. Oh wait.... you haven't worked there before? You didn't work side by side with the engineers who were given the task to redesign all the AC Delco plugs to be manufactured in the Honeywell plant? You didn't deal with engineering issues on a daily basis in the Honeywell/Autolite R&D lab?

You obviously have no idea how it works. Nothing is split. Lines what model/part/type of plug their making daily, if not more. And Honeywell makes the majority of AC Delco plugs, I don't recall the exact % but it's somewhere above 70% of the entire AC Delco line, including several iridium models.

sure, synthetic is alot higher quality oil than dino oil. check out this site www.bobistheoilguy.com its all about car maintenace

[01cherryreds10]

But won't synthetic blend or full synthetic oils cause harm to the seals?

[dimerunner88]

no,as a matter of fact most of the time its better for them

[350X]

But dino oil is more eco friendly, it comes out of the ground, so when your done with it, you can just pour it right back where it came from.

Plus dino oil is solor power generated. The sun grew the plants, that feed the animals that feed the other animals and when all 3 died, tunred into oil.

You can't get no greener then that.

and yeah, your right . . . it's about 65-70% ac delco
people would be surprised how many part #'s come off this production floor and the order they come in. one minute might be an AC line and the next your running a motorcraft part and then back to a AC again.

remember i told you about fortoria shutting down? they finally are, we got the last few machines a week ago.
