AC Spark Plug Application Chart
 

I pride myself on being able to find just about anything on the internet, but this one has beaten me. Does anyone know a site that has an application chart for AC spark plugs? I purchased a lot of NOS plugs and would sure like to know what they fit. 43, 45, 45XL, R83CT, C86, R45XLS, R45XLS, 85TS, R43XL and many others. I need a chart that will let me enter the plug number and tell me what engines it fits. Thanks, Larry

Sam, I don't think I have any 44S plugs, but I am at work and the plugs are at home. I will check when I get home and let you know if I have any. Thanks, Larry

Larry,
What stripe pattern are on the plugs you have? 3 or 4 green bands, etc? Thanks,
Rick

Re: AC Spark Plug Application Chart
 

They all have 3 thin green stripes and 1 wider green stripe.
Thanks,
Larry

I do have some 44TS, in two sizes, what seems to be a common size and one that is a little shorter

Thanks Larues. The stripes among other things denote
year(s) of manufacturing. I don't have a clue what years used what stripes but know the late 60's early 70's used the 4 narrow green stripes from what I have been able to find out and they are VERY hard to come by.

Found this for you.

Re: AC Spark Plug Application Chart
 

So many Vehicles used those spark plug sizes you listed,that it would be easier to list the ones that didn't use them.
The AC three narrow green ring and one wider top ring spark plug design was first released in 1972,and continued to be used for years after.
