I make a habit of checking the general state of tune on most vehicles that come into my shop. Certainly, I've seen well-done plugs of all brands, but it seems that Autolite plugs (which account for at least 30%, maybe closer to 50% when the plugs aren't OE) always have more electrode wear without corresponding external indication of age than other brands, and I seem to get as much or more improvement after replacing a set of plugs (I use NGK whenever possible) when Autolite is what came out vs. other brands. Is it just my own dislike of cheap parts and the kind of people that put them in (and don't get them tight, or get them too tight, or compliment them with cheap filters, or... I digress) or are Autolite plugs really a poor quality part in general?

On all the vehicles I've owned or worked on my 3 go to plugs are Motorcraft, Autolite, or NGK. Autolite is a good product.

I have used them in the past, but only their copper plugs for ~20,000 - 30,000 miles. No problems with them in that time frame.
I have read of many problems of Autolite Platinum and Iridium plugs.
I don't use them anymore.

Fords only get Motorcraft.
GM get Delco or Bosch.
Asian, usually NGK or Denso.
I know for a long time my Dodge/Chrysler stuff ran well on Champ plugs, but it has been a long time since I have done plugs in one.

I've been running 16 Autolite XP plugs that were $2 / plug after rebate when I bought them for 2 years now in all climates from the Great Lakes to deep South Texas with zero problems. Originally warranted for 7 years & unlimited miles at time of purchase, now lifetime warranty. Zero complaints from me. Guess you don't like me. I run Fram Tough Guard air filters and middle or top tier oil filters, and don't see a difference in transmission filters for my truck except some of the Asian ones now have red (silicone?) ADBV instead of black nitrile in the spin on element. Currenyly installed is ATP B-245 I caught on a weird pricing cycle on Amazon for $12. Oil has typically been PPPP since I bought it. Coolant was drained & filled with Zerex G-05 if you have an opinion on that - concentrate mixed with distilled water.

Guess you have a few paradigms I don't fit. I like quality but don't see why I should spend more than necessary.

I'm thinking your right...


Around 20k on the set. Had a random misfire on startup and in general didn't run right. #4 had a U-Shaped crack also. Put Motorcraft's and it runs perfect now. I was always told Autolites and Motorcrafts roll off the same line, I'm having a hard time believing that now.

Eric, the condition of the threads on that plug is what makes some people (ME!) want to coat them with something. That's one worn pluggie-poo.

That's a glittering generalization.

I use NGKs in my vehicles. Went to buy the Autolite Copper ones for my Liberty once and they were Chinese made. Got the NGKs (OEM) and they were Japan or American, can't remember.

I used to run Autolite plugs exclusively. And I've got a fleet of vehicles to maintain that is costly enough that I actually got a Christmas card from RockAuto several years ago that was hand-signed by about 10 people that I'd never heard of or ever been associated with.
That said, my last three plug changes have seen used Autolite double platinum plugs that have a seen a huge gap. They engines haven't had a misfire and I really didn't notice any performance gains with new plugs. But the gap was much larger (for the miles on the plug) than it should have been.
I have started to experiment with other brands, especially since I've seen new Autolite plugs from questionable COOs.
Motorking, I know Fram and Autolite are not bed partners like they used to be, but since you've bashed filters that come from the Orient, would you care to comment on Autolite plugs made in the Orient?

I use Autolites almost exclusively and have nothing bad to report. I was a little concerned with the transfer of production to Mexico and China but I have not witnessed any quality issues to date. I also will use NGK and Denso from time to time. To be honest, I've never had an issue with any spark plug brand - they all go bang when needed - except for E3. Those are a terrible overpriced and underperforming gimmick plug same with Pulstar.

The Iridium Autolite XP plugs I'm running in my 5.7L Hemi were made in Mexico, which at least is in this hemisphere. Factory Mopar plugs copper plugs were NGK calling for replacement of all 16 plugs every 32K miles. No way that's happening for me!

You are so right! I have had three Jeep 4.0 over the years and all ran better on Autolite plugs? Don't know on the newest ones either.
