Ok, I would like to try a colder spark plug. I am running Autolite ASP 46. When I ask for a colder plug, do I ask for a ASP 42 or ASP 50?
Thanks, Ken
Thanks, Ken
Lower is colder.

If i'm having detonation problems under load could having a colder plug help? I ask just because i'm planning on running my falcon at the all ford powered drags this sunday in sac.
I plan on putting premium in it (usually run standard, or plus) and advancing the timing a little cause it runs way stronger if i advance it.
This hope is somewhat a last hope because i already know if none of these fix it its just the stupid distributor and its vacuum advance (loado
).

Harry,
Are correct, I called Autolite and told them my problem, well not all of them, just the pre-ignition at 60mph cruise.
They recommended AP45's or Platinum AP124's
NGK Recommended: ar6fs stock Number3323. Which I am getting today.
Advanced Auto has them. I'll follow up with a pinging report.
Thanks for your help,
Ken

Add Champion: RF10C and RF10.
I hope the plug info can help others that are having the same type pre-ignition problems that my 250 has.

well, I had a good end to today. I got the plugs, and installed them. I think my first problem was a HOT plug, Champion RF18YC, I found an autolite box in the garage. Had a little ping, good but not good enough. I rechecked my timing, it was 12degrees, hmmm, I let it yesterday at 10degrees, but I did remove all the vacuum plug caps and replaced them with thick rubber ones.
I dialed the timing back to 10 degrees and drove it again, still pining.
I disconnected the the vacuum port on the carb, and drove it again. Little ping this time. I then turned the vacuum module on the distributor counter clook wise until it clicked, then 1 turn clock wise. I drove it again, and no to little ping. I turned it out 1/2 counter clock wise and tomorrow I'll drive it again. If it slightly pings, premium gas time. I am also going to readjust the rockers just incase it's the old lifters.
If I could get a good picture, I would send in my damaged plugs. Yep, there on the ceramic. I'm hoping there is a colder plug then the NGK I have, I will try them out too.

Ken.I don`t mean to be rude,but you put your finger on it.Champion plugs.SORRIEST POS on the market.Have NEVER been able to get more than 6000 miles out of a set.And usually 3000 to 3500 is when they die,and I mean that LITERALLY.I have had several different vehicles that I have owned just shut down and refuse to start using Champions.
Champions:MAJOR WASTE OF TIME AND MONEY.
Best plugs for Ford?Plain old Motorcraft coppers.Cheap as hell,last forever.

Leo, your not being rude.
My problem is/was people post, "you need a colder plug", without saying what the option is. I have played with cars for ~30 years and today I finely looked up, how to read the plug part number. I just thought I would post, for the other people that were like me, not knowing what a colder plug p/n is. I'm tired of just relaying on the PepBoy.
The plug info is probably obvious to most of you, just not me.
Just my thoughts,
Ken
The odd plugs were in #4, it was glazed, #3 had some ceramic pitting. Those are suppose to be rich, or at least, to me.

You are not rude when you're right. Champion has always been the most 'hyped' and the worst performing plug on the market. How ever bad they are, there are expensive ones that are crap too like NGK. But, when my engine started running bad I pulled the plugs and found massive brown deposits with two plugs actually bridged, and these were Autolites! They hadn't been checked in 28000 miles so I guess the real answer is to check them more often! I used to, but got used to modern engines not needing replacement for longer periods. I'll see how the new AP45's work in the new set up.

FYI,
The Champion is made with a softer alloy. The intent used to be that while the engine was running the sluffed off alloy from the plug whould help atomization. That is why that don't last. And, if that were true you would see an increase in mileage.
I had played with this many years ago and did not see a difference. The best bang for the buck for mileage/performance is old fashioned maintenance.
Good luck and let us know how it turns out, Ric.

Harry, the NGK's I bought were only a $1.95 each. I didn't check out how much the Autolites were.

I havn't bought any NGK's recently. Last time was about eight years ago. Bought 'em for my boat (Mercruiser 260 GM V8). They were about $3.50 each then, and they only lasted about half the summer. Replaced them with Autolites. I didn't replace those for two years!
Maybe they are better now, but then they reminded me of Champion plugs.

I'll be happy to let you know if they are POS, in 3000 miles.
