Spark Plug poll

[mikepmcs]

Just wondering what everyone runs and prefers for plugs. Any suggestions, advice and free knowledge is always appreciated.

Interesting topic I often wonder what are the differences in "spark plug" brands

And it is also interesting that champion is one of the highest on the poll?  

[terrible one]

Autolite for me.

[TruckDriver]

Autolite for me.

[dodgeboy67]

ANYTHING BUT DELCO......I GENERALLY USE THE BOSH, BUT IVE HAD REAL GOOD LUCK WITH THE AUTOLITES TOO

[WM23N1]

Autolite here.

I have been part of 2 dyno tests changeing just plugs. One on a race bike the other a car. There was so little difference between brands and types of plus it is not worth showing the charts. NKG's did have a slight edge. The best thing you can do is just change them often has a new set is always best.

[Ghoste]

I've been using Champions for years and I've had no problems with them.  Until I do or there is conclusive evidence of something else being better, I'll continue to.
I tried Accel U-grooves once many years ago and didn't like them (but I honestly can't remember why).

[Big Lebowski]

Autolite 85's You can't tell it's a Ford part.

[RD]

I believe neil addressed this question a year or so ago and stated that he did a dyno run on a hemi with only changing the spark plugs and champions yielded the highest HP and Torque numbers of all.  I believe he used three different types.  I dont remember the other types, just the winner

[mikepmcs]

Champion baby!!!! Mopar friendly!!

[Dave22443]

I like the Autolites myself.  I've run Champion a lot and they are fine, just that the Autolites seem to last longer for me.

Now if you really want to start an interesting poll, ask what oil filters (or oil) we use in our cars.

I run Champion in all my Mopars. I tried Autolites one time and it was a mess. They didnt do very good.   My daily driver Honda Prelude went thru a tune up a few years ago and it calls for NGK plugs but I decided to get the Champions for it. I had nothing but troubles with the Champions. The gap kept opening up on them and the car wasnt that smooth when running.  Just seemed to not run well.   I decided to spend the $ and get the NGK plugs it actually calls for and it was night and day difference in how it ran. Way better and I havent had to re gap them at all. I will go with NGK next time for sure on the Honda.

Some of my chevy buddys laugh at the Champions., They cant get them to run good in the chevys.


We spoke about this one a time long ago and I dont know if theres truth to it or not but ignition systems from the various manufactuers are designed with a plug in mind and thats why certain plugs seem to work better in some vehicles and not others. A resistance in the plug to go along with the ignition systems.   My parts store owner/friend says there are 2 different Champion Plugs out there. The ones you get at an auto parts store and the others you get at K mart or Wal Mart. They used to have a spark plug machine that would test plugs and you could see a difference between a parts store and a discount store plug.


Anyone else ever hear about this theory on plugs and ignition systems?

[Silver R/T]

NGK is one of the best plugs, unless its not made in Japan

[ChargerRob]

Champion Plugs all the way.

[squeakfinder]

I don't know why. But it seems like Champions have always held up longer for me. I do run a step hotter though on the engine's that are a little worn out on my Mopars or Chevy. I usually can get away with cleaning them 2 or 3 times before replacing them.

[Brock Samson]

 Champions.
..interesting for sure but just how often do you change plugs?... 

hell of a stance there on Frankie Todd... 

[charger_lady]

Only Champions for our 69 Champion...I mean 69 Charger...lol

[firefighter3931]

NGK is a superior plug...luv em ! 

[adauto]

Autolite or Bosch depending which car I'm workin' on.

[sixty6charger]

Bosch platinum have worked very well for me. nice burn.

[BLACKWOLF]

I USE ACCEL U-GROOVE

[mikepmcs]

thanks for all the input. champion seems to be the plug of choice.

[Nacho-RT74]

I won't vote since I have allways used J12YC Champions and is not fair vote for them since I have not compaired( I wish to find Rs series because the radio noises, but haven't had success down here ), but I have to admit that I never have noticed nothing weird with Champions... never had as far I know a spark plug problem related.

somebody can post the J12YC equivalents on rest of brands...

I know autolite is 85, but the rest ?

I will cross them at work tomorrow and give ya some equivalents. I run champion c57cx's

[Kirkvkid]

I don't have much to add here, but a few years ago I threw some Bosch platinums in my truck and it ran awful.  The platinums were all they had in stock to fit the truck, don't recall why I didn't go somewhere else.  It ran so bad after with the tune up, I figured I messed something up.  I could figure it out and ended up going to the stealership for them to check it out.  After a day or so they figured it was the plugs I used.

 
Anyway, I don't know about any other applications but, i know at the time my 30,000 mile 94 dodge ram with 318/auto didn't like them.  Maybe this can help someone avoid some aggravation someday.

[tan top]

i always run champion plugs in the 440 , except the last plug change , NGK's went in as that was all i had on the shelf , on that sunday afternoon, ran real good also. when i checked the plugs after a good full throttle blast they were slightly a lighter shade of brown compared to the j12c 's that came out.

[HDCharger]

Champions.

[chrisII]

I prefer champions, but as my dad told me years ago autolite is made by ford so they run better on oil burners   

[Ghoste]

Are they still made by Ford?

[mikepmcs]

autolite was never made by ford as far as i can tell but ford promoted and actually was in a lawsuit one time about the autolite deal.

here's a read for you, i'll try to find the law suit too

Your first link states that Ford purchased Autolite in 1961 and sold them to Bendix in 1973.

semantics, i was merely saying ford did not manufacturer autolite. i know they owned em'.  so i guess from that year to that year you are technically right on, my bad.
