Autolite Spark Plugs

[mike42]

Does anyone have a comment on using Autolite Plugs in a '40 85 hp ? I've used them in other cars in the past with good luck. Just wondering !

What is the proper plug ID number ?

Thx.....Mike

I use Autolite 216's in all our Flatheads, except the ones with aluminum heads, for the aluminum heads I use Autolite (CRS strikes again) I can't remember the # but I'm sure someone will post it. I have always had good luck with Autolite plugs.

The Autolite 437 is the best plugs for that motor. That is what I think anyway! Slighty hotter than the Autolite 216, either of these are better than Champion H10. That is what I think anyway!

Thx guys.

To make a head puller, I need to remove the innards from spark plugs so that I can tap them for all thread.

Removing the innards from Champion plugs is relatively easy while the Autolite 216 plugs are darn near impossible. They are just too well made.

Whether that makes a difference to plug performance in normal use I don't know but I suspect that the Autolite plugs will last longer.

Thanks, I don't know what happened this morning, but I couldn't remember that number... Its hell getting old and, according to my wife, the mind isn't the first thing to go...

[mike42]

I went out and bought the A216's to give a try.

Thx

I put my newly all rebuilt 59-A in my '40 pickup with everything new. I put in Champion h-10, darn thing didn't act good at all. I finally took them out and put in a set of Autolite as someone recommended, the motor just purred and runs beautifully. Good product, good luck with yours. Jack

[mike42]

Thx Jack. I'll let you know later this morning if she purrs !

Seems like all that Champion H-10's are good now is lawnmowers.

[mike42]

Thx

I've been using Autolite and NGK plugs for several reasons, but the most important is: the Champions H-10 had a cur thread and were hard on aluminum heads. The other plugs had rolled threads and were a little kinder than the champs.
I don't know where or how their made now.
As a side note I bought a set of Mexican points for my SBC dist and the regular price for them is over 62 bucks and the little Allen wrench too de oesn't fit. lucky it has a screw driver slot.

What's wrong with 216's in aluminum heads?

[Ol' Ron]

Nothing, they work great. It's the Champ H-10's you have to watch out for. read the post.

Only use Autolite in my Flatty.

[Ol' Ron]

A word of caution here, the plug reach of the stock heads and the old aftermarket heads was 7/16. The new Edelbrock and Offy heads take a 3/4 reach plug and here's the rub, some of these plug selections leave several threads exposed to the combustion and can cause pre-ignition. These few extra threads can be removed with a 45 deg countersink.

we used to use AL7 and AL7X

I have used Autolite in my flattys for 50 years. They work great!
