[bobpo1]

What do most of you feel are the "Best Plugs" for a stock Model A..??

 

[Gary WA]

Depends how you drive. I Use 3x repos.

 

[J Franklin]

It depends on what you are going for. In my barn find Tudor, I have the original plugs (champions) that work just fine. In my truck, I have new champion "go plugs". In my tractor, I run the standard fomoco plugs for a's. All seem happy.

I don't think you will find an universally accepted "best plug".

I use the 16y's. The work, cheap, and look beefier then the autolites. Are they better then the autolites, no. I just like the looks of them.

Re-pop 3x champion seem to chew their way through pretty good. Got them as a gift, an expensive gift.

CLEAN PLUGS is always best.

I like the discription... "Champion Racing Plugs Power More Race Cars To Victory Than Any Other Spark Plug."

Now you can tell everyone you have "Racing Plugs" in your Model A.

W-18

But only if:
• you use 15/40 Rotella
• you have blackwall tires
• you have a 160° Thermostat
• you have a 12v alternator
• and an overdrive
• A/C is optional

The O'Reilly description stated a plug gap of 0.033" to 0.038". What do you use for Model A's? Isn't .018 to .022 recommended?

 

[djlanier]

Please disregard my earlier post, obviously I was thinking of points. However I am interested in what you use for spark plug gap if you run a high compression head.

Will these work with juice brakes?

Haven't tried it, but probably not.

I have the best free spark plugs-- 3X, got 2 sets from the trash at Hershey, lifetime supply , I run the car lean enough to burn black fouled plugs clean and white

A good stock coil should fire the plugs fine with .035" gap, but many will cut back to .025" to .030" just because the higher compression takes more voltage to jump the same gap. The wider the gap, the harder the coil has to work, but it will more easily fire a lean mixture with the wider gap. I've never had any spark miss by using .035" on my stock head, and I'll probably try .030" gap on my 5.5 head when I install it.
