Re: Which plug do you run?
 

We have always used the Champion plug also. Never a problem. Enjoy.

Re: Which plug do you run?
 

I run w16Y's as well-what gap setting do you use?

Re: Which plug do you run?
 

Gap set at 35. Enjoy.

Re: Which plug do you run?
 

I've tried quite a few but 3x in my A,it's happy!! And so am I.

Re: Which plug do you run?
 

I'm running Firestones but only because they were in it when I bought it. They run fine so far I've driven maybe 1500 miles.
I'm going to put in the Repo Champion 3X's soon.

The Champion #518 (W18) run nicely in h.comp. heads at .030/.032

See Larry Brumfield post of 6-29-10 for info. on plugs.
YBlock, our 5.5 w/ W18's (new no. 518) runs a nice tan color and the price is right per plug. We ran TT10's for awhile and the car likes the 518's with a Marvel carb. Note this is w/ FS zipper ignition which we're going to change back to modern points due to advance issues on hills and see how that works. Also, I use small amounts of lead substitute and ethanol stabilizer in gas (but not sure how much effect that has.).

Lot's of discussion/opinions about heat range, etc. We tried different plugs we had on hand to see what works for our set up, so others may have different experiences.

ANYTHING with the right heat range & burns CLEAN!
There are NO "MAGIC" Spark plugs!
Driving with "GUSTO", helps to keep plugs running CLEAN.
LOOOONG idling sessions crap them up.

I use restored Champion 3Xs in all my stock model As.

Re: Which plug do you run?
 

37 years and 40000 miles on the same set of reproduction champion 3X and see no need to change.

Re: Which plug do you run?
 

3X run the best for me.

Re: Which plug do you run?
 

Anything but new Champions.

Re: Which plug do you run?
 

Champion W-18, run them for years, good plug....

Re: Which plug do you run?
 

Interested in your comment. Why? What problems have you had?

Are you talking about a stock Model A engine? Enjoy.

Re: Which plug do you run?
 

Champion W18 here. Same as JD1931 says.

Re: Which plug do you run?
 

Same here Champion W18 4,000 miles and they look new. Good Power curve 16 mpg average.

Re: Which plug do you run?
 

Same here with 34,000 miles.

Re: Which plug do you run?
 

I am having no problems.
I have used both the champions and autolite, but prefer the champions due to their size/looks.
They seem to have a better appearance on top of the engine then the skinny autolite plugs
I was just curious as to what others were running.
And yes, I am totally stock.

Re: Which plug do you run?
 

I misunderstood you post. I like Champions to, for your same reason. Sorry. Enjoy.

Re: Which plug do you run?
 

Went to advance auto and got their cheapest, TT10s. 50,000 miles on the same plugs. Works for me! JB

Re: Which plug do you run?
 

I'm cheap, free plugs, champion 3X, picked them out of the trash at Hershey, were black, ran them lean and hard, now burning near white

Re: Which plug do you run?
 

Hello Gang,

My car is currently running Champion C-16 C plugs. I pulled them out and they look a little worse for wear. The center electrode is noticeably worn out near the ground electrode. I planned on replacing the plugs with Champion 3X's as recommended here.

Should I have any concern with such a swap? If I should start my own thread for this question, I will. Don't mean to step on anyone's toes.

Thank you for your time,
Ted

Re: Which plug do you run?

Re: Which plug do you run?
 

Champion W-18 for years...

Re: Which plug do you run?
 

I've had good luck finding piugs sold as racing plugs from the 30's and 40's... authenticity and still a bloody hot fire

Re: Which plug do you run?
 

I've been running either 3X's or W18's (518) for years and here is a picture showing one reason why. Don't try this at home unless you have a lot of hacksaw blades.:D

Re: Which plug do you run?
 

Mr. Swoft, A "Blast from the Past". How are your doing I haven't seen you on here in a while?:p

Re: Which plug do you run?
 

I am still running C 16 C in the car that I restored in the 70s, probably the key to all of them is having the mixture right.

W18 at .32 with HP head.
