Default F10 champion plugs

Has anyone used F10 plugs in their Y blocks? I have a lot of these plugs, new, in boxes and thought I would try a set In my 292. If so any problems? Thanks

That seems to be a colder plug than the y-blocks used. 10 versus 18 for the Y-block. I think those were used in Ford I6 engines beginning in the early 60s or so. It's harder to tell now days since the F10 spec is long ago obsoleted to RF10C. Y-blocks would use the RF18YC. Both of these may now be considered as obsolete. A lot of folks changed over to other brands for one reason or another.

Heat range varies with manufacturer but with Champion, I believe the higher the number it is the hotter it is.

I read something from Ford that in the early 60s these were used on HD 292's? If you google search you can find some of the old manuals and all...

f10 is on the cold end of the scale and F14Y, 870 is on the high end. f10s were used on some Ford engines in the mid 50s. Yes, higher the number hotter the plug for Champion. I have nine boxes of new F10s and thought I would try a set, so just threw out a question to see if anyone has used them in their Y block and how did they run? I do have a 1958 master Champion plug catalog and it shows some Ford trucks and tractors used the F10 plugs

Default F10 Champion

Might be worth trying them. What are you using now? I've heard that in the points & condenser days, the spark plug heat range was a little on the high side to help prevent fouling in ordinary city driving. That sort of stands to reason. They might be suited to summer highway use or something along those lines.

Can't really hurt anything with too cold of a heat range plug, the worst that will happen is fouling. Excessive heat range is different, can cause pre-ignition.

I’ve been using autolite 45s for years with no issues. Just thought I have all these new F10s why not try them out, doesn’t cost me anything. I personally will not be around to use all the plugs that will be on my son as he will inherit the truck. It does have electronic ignition.

Before they discontinued them, I used Champion UF-11YC spark plugs in my 272 and later in my 292. After that, it seems like they recommended using Champion F-14Y plugs, but all that happened decades ago. Never even heard of an F10 being available, not in my area. They all have the same thread and seat which mates the Y-block heads, but the higher the number, the hotter the plug.
Never had a problem with any of the ones I used. If the 11's were still around, I would still be running them today. Same plug can be used on the 223 I-block 6-cyl, so no matter which car I'm tuning up, I can buy the same plugs.

Wonder when Champion stopped manufacturing the F10 and was it replaced by a new plug. Do new F10s have antique value?

I never heard of 'em, but that isn't saying much. They are tapered seat though, so I thought they were a little more "modern"?

The F600 with a 292, a five speed and a two speed were driven at wide open throttle against the governor through all gears, all the time. They used a colder plug because of that. This started in 55 and those trucks were driven like that until they dropped one by one and were replaced with T750 and 850 with 477's and 534's.

Well I’m assuming they aren’t worth much so I guess I’ll try a set in my 292 and see how it goes. They have been sitting in my shop for 40-50yrs and don’t remember where I got them from

Can't say exactly, but I can remember getting my last set of Champion F14Y's in the late '70's. At that time, the F11YC's had already been sold out. However, the F14Y's may have long since been discontinued, but the auto parts store still had a lot in stock.
I can remember the auto parts store clerk mentioning that the lower number Champions were listed in his book for heavy duty trucks.
The last year Ford marketed the Y-block was in '64 and only for trucks. It's possible I was getting the last of a discontinued set of Champion F14Y plugs in '78. In '74, the last new Y-block (292 truck engines) were 10 years old. I still obtained F-11YC's back in '75, but that was the last time they were available here, then had to go with F14Y's and that was all that was available for the Y-block here.

Exclamation Re: F10 champion plugs

... hmmph ...

Stumbled (before beer-thirty) across this in the 1957 FORD TRUCK WSM -

CHAMPION F10 SPARK PLUG -

ECR 272 ENGINE (HD) - 302 -332

It equates to AUTOLITE/MOTORCRAFT BRF-22 (also BF-22 which was a RACING PLUG in the day).

It is a cold plug.

Kultulz, your opinion if I throw a set into my stock 292, any issues to look out for?

Post Re: F10 champion plugs

IMO ...

The plugs are too cold for street. For instance, the FORD AUTOLITE BF-82 was intended for the six and FYB. The BF-42 for the FE. The last two numerical characters give the heat code for the plug.

The BF-32 was used for HIPO street, but it was used with high compression and IGN LEAD

So you see the extreme. They will cold carbon foul.

Thanks for the information, I’ve got 9 boxes of new F10s that I guess would be suitable for a hippo Yblock if someone would be interested in them.

Actually they will work in any FORD engine taking 18MM plugs calling for that heat range.
