What Spark Plugs

Recommended Posts

Hi all,

So what spark plug does everyone like to run?  Changing plug this week, so thought I would ask.  Factory says AC 44s, is this a medium heat range plug (haven't looked it up yet)?  I've used Champions a lot in the past.

 

Thanks,

Use the AC44s plug. I'm in the car repair business for 44 years and we've seen a lot of instances of Champion

plugs having the  bottom end of the plug come disassembled with the porcelain shield around the electrode 

coming apart and falling down. I have seen defective AC plugs every once in a great great while but it is extremely rare.

My favorite plugs other than the AC plugs are Autolites. They are economical to buy and I've never seen a defective one ever.

I use these in Chrysler and Ford products. I use NGK in the Asian brands with no problems. When customers ask me about Champion plugs I tell them I wouldn't put them in my lawnmower, let alone my car.

Something many do not know what the A/C & Champion stand for.   A/C = Albert Champion & Champion = Albert Champion.....

I have been using AC45's. I had a big bag of black 44's.

 

I do like the NGK's and have been switching over to them since I had the V-12 Jaguars about 10 years ago. Haven't put them in a Buick Nailhead yet, though.

I have been using AC's in my Buicks and NGK's in my snowmobiles for many, many years.  Both have been flawless.

Thanks.  Found some 5 AC 44s plugs on ebay, need to find 3 more.  I guess they are hard to find.  May need to have a few sets.

Keep looking. I found most of mine on e-bay. There are some sets that are very highly priced. Resist the temptation. Cheaper ones will show up eventually.

You are right.  There a number of ones and twosies.  I think I'll buy some of them and stock up a little.  I also just checked and these are the same plug for my 67 Pontiac FB 400 (been awhile since I changed plugs in it, maybe logs 200 miles max per year), so it would not hurt have a few set for both cars.

 

Thanks,

Art, for my 63 Tom Telesco installed Bosch Platinum plugs set at .0050. I am delighted with the tune up performance updates Tom completed. The distributor was rebuilt and electronic ignition updated. Tom gave the carb a rebuild. Since the updated tune up I can feel for the first time  the 2nd two barrels kick in on aggressive acceleration.

Tom said the Bosch Platinum plugs are good. I agree.

Hi Jim,

 

I conversed with Bob this morning and he is in Boston right now. I have the number for the Bosch plug that I had saved from a previous conversation on the forum. Bosch 4036, I also have seen an alternate number associated with this WR9FP.

That is correct Bill & what I normally use.  They require 1/2 the voltage to fire. Are a Multi Hear Range plug that adjusts itself automatically. VERY resistant to fouling & last just about forever in our applications.

Tom,

 

Bob mentioned a different plug gap than what is given for our application. Is that because he has the electronic ignition which calls for a different gap? Thanks.

No Bill I used that gap when I was using points in my '64 Riv.  Remember they require 1/2 the voltage nec.  You DO NEED good plug wires though.

How does that work?

Same question.

Can't answer those questions as I have no idea.   It's what I've read & been told.  ALL I have to rely on is my experience as an auto tech for the past 60+ years IF that means anything to anyone.

Jim, Bosch 4036. Tom Telesco has some. The plugs have been discontinued. According to Tom the plugs have produced  good results in the many cars he has installed the plug.

Wait a minute!!  Are you really saying a gap of .0050 or is it .050, there is a huge difference here?

I think Bob just held the 0 key a little too long. I have talked to Tom T. and he has told me the gap is 0.050 as opposed to 0.035.

Haha, I thought so, but nobody was asking, and they were talking more about using the same gap, but never mentioning the gap size.  All is good..

Art, you are right it is .050 (50/1000). My mistake showing 50/10000 with .0050. I played a lot of football without a helmet.

Turbintor,

Art, being mistaken and admitting the error at my age doesn’t smart nearly as much as when I was a boy in Math class. 🤓

Thank you for bringing the error to my attention. I’m much better at calculating ROI over a given time period.

Steve, personally the tune up chain is as strong as your weakest link. I’m certain your NGK plugs do what they are suppose to do when all the tune up components are in sync. There are many ways to get where you want to go. The forum certainly has helped me quite a bit.
