1926 Oakland Spark Plugs

Recommended Posts

Hi everyone, we have a 1926 Oakland and are looking to find out what the original spark plugs would have been for it. Does anyone know where we could purchase plugs the same as the originals or what the code for them would be? We have a couple of service books for it but they only say clean and/or adjust gap. It currently has Champion W16Y plugs wich somebody put in before we recieved it. Thank you all in advance, any help would be greatly appreciated.

26oakland,

Welcome to the AACA Discussion Forum. I have moved your post to the Technical Forum. Hopefully someone here will be able to help you. If not, we can try the Pontiac/Oakland Forum down a little bit lower on the page. I suspect someone will be able to help you soon.

Since Oakland was part of GM I would bet that it was supplied with Champion plugs since A.C. Champion was associated with GM for many years. Now what number plug I don't know, someone probably has a cross reference manual.

The Champion book I have lists W16Y as an application for Oakland thru 1929, cross reference to AC 78S. This was an older book so there may be some changes but at least it is a start.

AC Spark Plug and Champion spark plugs are different companies. AC Spark Plug was started when Billy Durant brought Albert Chanpion to Flint to build sparkplugs for his Buick and then GM cars,etc. That is where the AC (Albert Champions initials) came from. Champion left Durant and started his own company, the Champion Spark Plug company.
