1930 Packard Std 8 Spark Plug interchange

Post by n2oldthings » Fri Aug 06, 2010 7:55 pm

I was wondering if anyone could tell me if there are any spark plugs for other makes of cars that will work on the 1930 Packard Std 8 engine and possible cross reference numbers to look for. The ones in the car now are Champion C-16 C, I believe they are 7/8" threads. Any suggestions to vendors that I could purchase the plugs from. Thanks.

According to the AutoLite website, AutoLite 3076 is the correct current spark plug for this engine if you have 7/8 threads, and AutoLite 388 if you have 18 mm plugs. Packards of this vintage also used 18mm plugs, but your Champion C16-C is a 7/8 plug. The AutoLite website gives current plug recommendations for most cars back to the early 1920s. I've been very satisfied with AutoLite plugs in my 34 Packard, but if you don't want them your local parts store should be able to cross the 3076 or 388 number to another brand. The other advantage of AutoLites if you're interested in authentic appearance is that they (at least all the ones I've bought) have black-oxide shells and not bright cadmium plating which would be incorrect for cars prior to 1955 or thereabouts.

Dave,
Thanks for the info on the plugs. I found some Autolite #3076 with 7/8" thread size like you mentioned on the internet. Ad said the plugs were for Hit Miss Engines, Model A fords, Fairbanks engines and John Deere engines. The picture of the plugs looked very similiar to my Champion ones in the car now.
