Correct - even Bosch makes some Delco spark plugs.
Autolite xp iridium enhanced vs acdelco iridium soark plugs
- Thread starter ziggy
- Start date
Always had good results from Autolite untill I put a set in an Accord this summer, along with new wires, and got a faint miss. Don't have tools or knowhow to check plugs so put set NGK's and prob solved.
All else being equal, I would go with the AC "regular" iridiums. They will work great and last a long time.
In my opinion your 22 year old Buick doesn't need anything fancier than iridium spark plugs.

Put AC Delco iridium plugs in my '02 Silverado when it rolled over 100K miles. Put another set in it just a few months ago when it rolled over 200K miles. I'll put another set in it again in 10 years when I hit 300K miles. The AC plugs meet the specifications for GM, are a good price, are readily available, and work great for my application.
I did my own research few years ago. When I got my lesabre,looking at a.c. Delco fuel filters, spark plugs,on amazon...one of 2 posted photos.also with Parker safety razors...plating was coming off after only 4 months of use the a.c. Delco fuel filter..4 months in.began rusting. Set of spark plugs appeared cheap.guy used them.don't remember what happened..but they feel it was made in china. Someone is using,a.c. Delco logo..but it isn't a.c. Delco quality.
I wanna try automate iridiums. I had a 95 neon once. 2005 or6,tried a set of new autolite spark plug wires.advance auto.immediatly,it interfeered with my radio in car. Put Chrysler ones back on radio worked fine.
There's a good lesson in "if it ain't broken" there. Also applies to the situation you're pondering now.
Lol.at the time,I had read bad stuff about EMF interruptions from sub par non one spark plug wires.this was one of them. So...pondered on the autolite iridiums.maybe should just stay with oem Delco iridiums.
The info I have is US models use NGK produced precious metal plugs branded Delco, some of their Euro models (no longer sold) may have Bosch or NGK branded Delco.
None from Champion or Autolite.

I bought a set of Autolite iridiums on sale, for the Tacoma 2.7. It calls for Denso iridiums but for such a crazy cheap price I thought I would roll the dice with the Autolites.

Either one will do I’ve had luck with both brands in multiple cars. If it was me I’d get the ones that would be like the ones that came out.
So..think it's safe,too but the automated from rockauto? Did some research last night..couldn't find anything that ticket to was known for selling fakes,like eBay and amazon. And read autozone,nuts direct from company..safe too buy spark pkygs,from rockauto?autozone? ..rockauto..$4.08 a plug. $24.00. $3.99 shipping. $32 total.Auto z one...$7.99 a plug.$48 then sales tax...
Rock Auto is safe to order from
When the parts arrive, google the return address. It will lead to the warehouse it shipped from. They usually come from warehouses that serve independent parts stores such as Auto Value, Parts Authority, and Factory Motor Parts. Sometimes they even ship directly from the manufacturer.
I see.feel safer going too auto parts store.still debating it.
A weary traveler asked:
But I'm on board with this fellow:
Keep your GM all GM. ;>
To which a wizened stated:
To which I heartily agree. So much stuff on a shelf is targeting your insecurities and wallets.
But I'm on board with this fellow:
I cross referenced a set of Denso double tipped wire-electrode iridium plugs. Double tipped as in there is a laser welded iridium "button" on the ground strap as well as the fine wire tipped center electrode. They were a recommended GM upgrade from platinum Rapid Fire ACDelcos. I got them for a smart price on Rockauto for $4/plug. I simply *DONT* want to attempt getting out plugs #5 and #8 anytime soon again in my Silverado....feh!
Keep your GM all GM. ;>
Well the autolites advertise,theirs platinum on the arm.iridium enhanced center. I read,platinum is a poor conductor of electricity. Amazon reviews...the majority,all have good things too say about a.c. Delco iridiums. But much less,on automate xp. A.c. Delcos, most think,have gone china.meaning downhill past decades.
I put a.c. Delco coppers in,like 3 years ago,20,000 miles or so.mechanic looked at them other day.said they were still very good. I see mmo and forgo top tier gas,and Lucas fuel treatment sometimes,every full up. It srems,autoli yes are not as good,as a.c. DElcos,or alone co pper! With citgo,I'm getting about 220 miles to a tank.mobile gas,and mmo/Lucas sometimes,247to 252 miles.so coppers s ,do work! In. A 3800 engine.

The electrical resistance of the tip material is irrelevant, but platinum is an excellent conductor. The majority of the resistance of a plug is elsewhere in the construction and is many times higher than whatever is going on at the tip material.
But again, platinum is a very good conductor of electricity.
Overall...would a.c. Delco iridiums,outperform,the auto lites? Be the same?a utilities less ?
