Spark Plugs for 1932 Std Eight


Recommended Posts

Curious what guys are using in their early 1930's Standard Eights for spark plugs.


These are 14 mm and originally AC-K9, K10, K12, etc.   This would cross into about AC-45, 46, 48 or so for various heat ranges for NOS plugs from the 1940's and 50's.  

But it's been pointed out that many of these NOS plugs have high failure rates due to manufacturing problems sealing porcelain at the time.

So I'd like to know what you are running now, either older NOS plugs or modern off-the-shelf plugs.  Name brand and model ( heat range).  

I have Prestolite 147 but they are too cold for me.  Looking for something else.


Thanks -- Scott
