awk409ak Posted September 19, 2019 Share Posted September 19, 2019 (edited) 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, Art Edited September 19, 2019 by awk409ak (see edit history) Link to comment Share on other sites More sharing options...
Seafoam65 Posted September 19, 2019 Share Posted September 19, 2019 (edited) 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.

telriv Posted September 19, 2019 Share Posted September 19, 2019 Something many do not know what the A/C & Champion stand for. A/C = Albert Champion & Champion = Albert Champion..... Link to comment Share on other sites More sharing options...
60FlatTop Posted September 19, 2019 Share Posted September 19, 2019 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.

Pat Curran Posted September 19, 2019 Share Posted September 19, 2019 I have been using AC's in my Buicks and NGK's in my snowmobiles for many, many years. Both have been flawless. 1 Link to comment Share on other sites More sharing options...
awk409ak Posted September 20, 2019 Author Share Posted September 20, 2019 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. Art Link to comment Share on other sites More sharing options...

awk409ak Posted September 20, 2019 Author Share Posted September 20, 2019 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 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.

Riviera63 Posted October 14, 2019 Share Posted October 14, 2019 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.

telriv Posted October 14, 2019 Share Posted October 14, 2019 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 T.

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.

telriv Posted October 15, 2019 Share Posted October 15, 2019 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. Tom T. Link to comment Share on other sites More sharing options...

telriv Posted October 15, 2019 Share Posted October 15, 2019 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. Tom T. 1 1 Link to comment Share on other sites More sharing options...

awk409ak Posted October 17, 2019 Author Share Posted October 17, 2019 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 Link to comment Share on other sites More sharing options...

Art 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 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.
